SLE rule?

Presently, in the market the model which becomes rule nonconformity after the rule conformity model and 08 has existed together.
As for photograph ion sport “GIGA XF400″ (high rally model)

From end of the last year, directing to 2006 season, the new product is announced successively from each manufacturer.Even among those as for the driver, there being with a first most influential commodity whose also interest of the golfer is high, the respective product appeals the flying distance efficiency.

And presently, the fact that it becomes first interest thing of the golfer, is generally known SLE rule.Being something which provides numerical standard in the provision of golf rule that with SLE rule, with “the spring effect (Spring – Like Effect=SLE)” (*) it does not become, coefficient of rebound (COR) of the club face, as for the te is the rule that not to be within n/a it does not become.

In the first place this rule originates in flying distance of the driver extending rapidly with the evolution of technology.Driver average flying distance of PGA tour has extended being 10 years, also 30 yards, presently to extend it continues.

distance of the driver continues to grow this remains, when i shot the middle driver arrived to near hall green…. per4,per5that, each2strokes,3provision that hit a ball on the green at the par-bats will no longer make sense.

distance of the driver up, is an important issue that may alter the quality of the sport of golf.

SLErule flow past

has decided to rule primarily in the u.s.USGAis, as a measure of distance driver to continue to grow, 1998coefficient of restitution in the year (COR) 0.83i decided that the numerical criteria.

from this, americanPGAtour the use of high-rebound club this exceeds the reference value is prohibited., most of the manufacturer’s lineup, fit model rules of so-called low-resilience (the following model fit) has become.

regulations governing the rules of golf in europe and japanR&Ais, USGAit was taking a wait and see attitude for this kind of movement, 2000announced the official views of a year that does not require numerical criteria.

by this, the world to golf club2one rule, 2it will be one standard exists.

lord of the japanese club maker, rather take advantage of the fact this situation, has released a driver exceeds the reference value high resilient unanimously. jump of a rule violation these drivers are you advertised the, also received great support from the general golfer, became miniboom.

current, USGAof Non-conforming Driver List (list of non-conforming high-rebound club rules) the majority of japanese manufacturers, club for the japanese market by foreign manufacturers or. japanese golfer stick to the temperament of distance of the driver has appeared in a place like this.

and finallyR&Athe judgment was that there should be unity in the world also numerical criteria. 2002years5a month, R&AandUSGA, agreement on basic policies and rules for spring effect rules of golf equipment is announced, for spring effect of the driver2008years1from mon, the reference value coefficient of restitution (0.830) more than to become a driver incompatibility with the rules of golf has been decided.

R&Ashape and of course it will also obey the golf world in japan under the.


2007the end of the year SLEcompliance with rules?

2007seal until years show compliance with rules

the driver of the photo on the right 2007the end of the year SLEand rule that the seal has been affixed. now see that a lot of drivers from around expressions like this last year.

this is, 2007end of the year, that is 2008amendment to conform the rule is the rule of the year i , shows that the. that is”fit”it has been referred to as, is that it is a high repulsive driver that actually exceeds the reference value.

it is somewhat difficult to understand. there was a double standard for, the driver in the field of sales, the fact that i will be going on this phenomenon, such as opaque.

the serious golfer is already limited…

prior to the rule changes, this year (2006years) from, JGA (foundation japan golf association) golf competition sponsored by the”high resilient”drivers are disabled.

JGAspeaking of organized, it is a flax such as japan and the japan open. the amateur golfer, there is no general relationship, JGAbut expert golfer (top professional and amateur) has been defined as intended for.

but, thisJGAthe game is expected to prohibit the driver due to the decision of the high resilient substantially increase the. be a fait accompli to be a violation club already, in the flow that has been banned in the game though few in number, high resilient means permit the use of drivers is because almost no.

you think the professional game to be banned most probably even competition sponsor.

golfer to participate in the competition but at least, 2008every game each year until, must ensure the organizer whether or not the driver is prohibited high resilient. i think there is an entry notice at the stage of course, premonition of trouble is happening so if you really care. in any case, this, processing is tentative until the total ban.


trend of japanese manufacturers

received the flow of such a rule change, fit model line-up rule has been focused on the various manufacturers of japan also finally. elements of the skip is, high resilient because it is not only, up ideas of distance seems to have been proposed in other parts of the face backlash.

2006of yearNEWfor the model, stance of each manufacturer is divided into two main.

1. lineup of products conforming to the rule only

08regulatory rules in anticipation of the enforcement of the year, manufacturer that only the model lineup was reduced to fit within the reference value coefficient of restitution.

example:
bridgestone TOURSTAGE X‐DRIVE 435 TOURSTAGE NEW Vi‐Q
tailor-made (japan) r7 425
mizuno MP－003 JPX E310
PRGR T3
yonex CYBERSTAR NANOV
daiwa ONOFF ONOFF PLUS
maruman METABIO

bridgestone and tayloraid, 06yearsNEWmodel is the model fit, expand at the same time as the high-rebound model was released last year, graduallypattern shifted to the model fit to go.

yonex is, 2001year jump of a rule violation featuring theCMhigh resilient model became the talk is cyber star3000 is, is the hit maker, some models already fit last year ahead of the competition rules cyber star NANOV has been released, there is an impression that manufacturers are sensitive to current events.

2. rebound at the same time, high-fit model lineup rules

full-fledged rule regulations2that it is years ahead, the grounds that the needs of golfers to model large high rebound, manufacturer has been both a model lineup and high-rebound model fit.

example:
dunlop ALL NEW XXIO SRIXON W－505
mcgregor MACTEC NVG2
calloway (japan) ERC HOT TOUR X－18 CF (model fit over) ERC HOT X－18 (high resilient)
nike SASQUATCH 460 TOUR (model fit) SASQUATCH+ 460 (high resilient)
honma golf BERES TW911 (model fit) BERES MG711 (high resilient)

the same model as dunlop and macgregor model fit , high resilient model of2if you are providing the seeds and, calloway, if the distinction between changing the model name, such as nike2there is a kind.

incidentally, these manufacturers are, needs of high-rebound model is as high at the moment.

are using their own driver’s?

current, if you do not know whether they are from and rule driver you are using will i do??

high-rebound club, R&AorUSGAhave been published from non-conforming club list will be determined by whether or not listed in the. in japan,, R&Aif on the list of08year will be from that incompatibility rules.

already this year also fromR&Afrom driver head list fit is issued, has been updated from time to time. this list isR&AandUSGAis jointly managed by the, 2008since drivers are not on this list will be all irrelevant rules. then for the first time, will be unified rules of world golf is swollen.

most club manufacturers, R&Asubmitted to the, has received the approval of the nonconformity-conformity.
compliance with rules/quick way to determine the non-conformity, is directly contacting the manufacturer has released a club of their own. why are you know their products well any manufacturer and rule, you tell me kindly.

distance drivers in the future

in my opinion, distance of the driver is not necessarily fall by the revised rules, considered to continue to grow in the future probably.

coefficient of restitution of the face is not only one element of distance up, future, other elements such as improvement of the shaft in position and center of gravity, and is made possible because of the twist-up distance.

therefore, in the sense of distance is up a brake on the original purpose, this rule amendment is expected to not only raised quite limited effect. also be considered sufficiently finally rules that have been developed over the years will no longer make sense.

when purchasing drivers of the future, 2008it checks if the rule is also fit since, to suit your own style golf, choice must be a driver.

if you want to use the driver a high rebound, 2007you should be aware that this is a limited period until the end of. let’s select the model and rule long if you want to use the club was purchased.

in any case wegolfers, good understanding of the rules be amended, position to comply with it have been asked.
