MIYAZAKI B.ASHA GOLF SHAFTS

Miyazaki released the B Asha Series of shafts in 2013 as an upgrade to the popular C.Kua line.  This line of shafts offers a lightweight shaft with incredible stability.  The 3R and 3S models come in a .350 tip.  The rest of the line has the traditional .335 tips.  The brown logo artwork which is a trademark of Miyazaki really stands out on the white background of this shaft.  The handsome graphics are original artwork painted specifically for the B Asha line of golf shafts.

MiyazakiFlexCodeMiyazaki Golf shafts are labeled according to an international flex code.  This code give a four digit number which explains the level of flex in each of the 4 regions of the shaft.  These regions are the Butt, Mid-Butt, Mid-Tip, and Tip.  Each of these regions are rated on a scale of 0-9 with 0 being the most flexible, and 9 being the stiffest.  A shaft code of 9842 would have an extremely stiff butt and Mid-butt region, and mid stiffness through the mid-tip region and a flexible tip.   These flex-codes help fitters match the bend profile of a shaft to a specific golfer type, or desired ball flight. The B.Asha Line of Miyazaki shafts varies in range from 46-48 grams in the 3 series, to 54 grams in the 4 series, 61 in the 5 series, and 75 in the 7S.  These are the lightest shafts that Miyazaki offers, and are ideal for Ladies and Seniors.  These lighter weights are ideal for golfers looking for a higher launch without sacrificing distance. In the B.Asha model, the torques of these lighter weight shafts were reduced from the C.Kua.

DevotedGolfer.tv editor Russ Ryden got to talk to Tim Gilles, Director of Sales for Miyazaki Golf Shafts at the 2013 PGA Merchandise show in Orlando. Part of that discussion covered the changes made to the Miyazaki B.Asha Golf shaft.

Looking at the bend profile of these shafts, they promote an active tip, especially in the 3R and 3S models.  Again, these are .350 tips, and do provide a stable tip section despite their super-lite weight characteristics.  The tip action promotes higher launch conditions without ballooning.  The 3 series maintain their flexible characteristics through the mid-tip, Mid-Butt and through the butt sections.  The international flex codes for the 3R (4222), and 3S (5433) models indeed give these shafts much more action in the tip and mid-tip sections.  In our range testing sessions, these shafts indeed launch the ball higher, but not at the expense of spin rates that were off the charts.  The higher launch coupled with lower spin rates from comparable shafts give these shafts a huge advantage in maximizing distance. We have found that the 3A and 3R shafts are ideal for Women and Senior’s who are slower swinging golfers looking to max out their distance.

The 4 series promote a stiffer mid-butt and butt section, with an active Mid-tip and tip region.  The flex codes for the 4A thru X series are as follows:  A(3411), R(5621), S(6732), X(7854).  The 4 series varies in weight from 47g to 53g and is ideal for golfers looking for a lightweight shaft that really launches the ball.  In range testing, these lighter weight shafts proved beneficial to golfers who have smoother transitions to the ball.  The Lower to mid stiffness rating in the A and R models coupled with higher torque in the Butt section and tip give the golfer plenty of feel in this lightweight model.  In Range testing, the model proved true to form.  Golfers really benefited from the softer feel of these shafts, resulting in more consistency off the tee.  Golfers with higher swing speeds who were looking for higher launch conditions seemed to really benefit from the stiffer models.

The 5 and 7 series are meant for golfers who have higher swing speeds looking to maximize ball Speeds off the tee.  The Stiffest models 5X and 7X have flexion codes of 7785.  These shafts maintain stiffness through the mid-tip region allowing for an extremely stable shaft that enables a higher launch with lower spin.  Range testing has verified this and golfers tested felt that the stability these heavier/stiffer models allowed them to” lean on it”, without feeling they were losing the shaft at the top.  On average, the golfers tested gained 15+ yards in distance without sacrificing dispersion.  That is huge when explaining the difference in a stable aftermarket shaft.

Conclusion:

Miyazaki has hit a virtual home run with their newest line of shafts.  The handsome graphics and colors really stand out, without being over the top.  From a performance standpoint, they do as advertised,
