Shaft Optimization Process

 

We use our own Shaft Optimized stepless steel golf shafts in all 1 Iron Golf clubs. Shaft Optimization is a proprietary process we developed whereby the playability characteristics of the shaft are optimized for peak performance in relation to the design specifications of the clubhead. This forms a perfect mechanical marriage and balance between the individual components which produces the ideal shaft loading and ball trajectory for the golf club regardless of the strength or swing speed of the individual golfer. While other golf club manufacturers concentrate on non-standardized flex ratings and other shaft performance myths we have found that shaft optimization is the major key to golf shaft playability.

 

We are also the only golf club manufacturer to perform shaft flex plane orientation as part of our Shaft Optimization Process. If a golf club is shafted without regard to the inherent flex plane of the shaft it will try and rotate around its axis to a position of stability during the swing which creates an oscillation between shaft and clubhead. This oscillation results in the clubhead literally wobbling through impact. However, when the shaft is correctly oriented in respect to its inherent flex plane it will resist twisting to any other position when placed under load and will remain stable and on-line through impact. The feeling is that the club-head is riding on rails through the impact zone. The result is a much higher degree of ball striking consistency with a maximum transfer of power at impact. It is important to note that over two-thirds of PGA Tour players have had the shafts in their golf clubs oriented for flex plane stability. This is an additional step that is not included in the  manufacturing process by any other golf club manufacturer.

 

Due to the precise balancing of clubhead and shaft resulting from our Shaft Optimization Process a 1 Iron Golf club produces much less of the vibration and shock normally associated with steel shafted golf clubs.  Consequently, our 1 Irons possess the comfort of a graphite shafted club with the inherent performance consistency of steel.  It is worthwhile to note that many of our customers are former graphite shaft players.

 

 

New USGA Groove Ruling

 

A recent USGA and R&A ruling on club face grooves will impact all woods/irons introduced after January 1, 2010 with loft angles greater than 25º.

 

The PGA has announced that as of January 1, 2010 they will adopt these new groove rules for all tournaments (includes virtually all professional tour events world/wide: LPGA, European Tour, Seniors Tour, etc – “elite competition”). The USGA has announced that the 2010 US Open will also require conformance with this ruling. For all other “elite amateur competition” USGA sponsored events (ie: US Amateur, US Amateur qualifying events, etc.) the rule will not go into effect until 2014. For all other events outside of “elite competition” such as club championships and for handicap posting purposes the rule does not go into effect until 2024. This “non-elite competition” category represents roughly 99% of all golfers.  

 

Lines of golf clubs that existed prior to December 31, 2009 (1 Irons and all other existing brands/lines) that were conforming to the previous groove rules will be allowed to be sold throughout 2010 (existing inventory) and will be fully conforming per the above schedule. Like all other golf club manufacturers we will be involved in re-tooling for this rule change throughout the first few months of 2010 and should be able to offer golf clubs with fully conforming grooves for “elite competition” by mid-year.

 

The new groove rule was adopted because the previous rules governing the dimensions of grooves allowed for an excessive amount of back spin to be imparted to the ball by the club-face. This extra spin resulted in a much higher degree of ball control and quicker stopping on the greens than the USGA thought fair (although these rules have been in effect for years). The good news is that you can still purchase irons that incorporate the old grooves during 2010 (until current inventory levels are exhausted) that produce this extra spin and ball control. Consequently, unless you are planning on playing on a professional tour or competing in the US Open you can use this stroke saving advantage through 2013 (if you plan on competing in the US Amateur Championship) or through 2024 for practically all other venues.

 

Just to be on the safe side, after January 1, 2010 you should contact the sponsors of any golf venue in which you wish to participate to verify their accepted groove rules.  You can go to the USGA website to read the new groove ruling in its entirety and to learn of any updates:  www.usga.org
