Driver Spin Rate vs Loft

[cometgolfer]

I think more loft will promote a better release motion. I find that a player of your caliber can benefit by increasing loft and increasing weight of the shaft. Loft at impact produces launch angle and shaft flex and weight produces spin. Try a 10.5 with a heavier shaft just to see what happens.

Jeff,

Can you explain a little more about the effect of shaft weight on spin? I understand the higher launch related to loft but I'm not sure I understand the weight impact on spin.

I fight a similar problem as Ed. I know better than to use an off the shelf driver, but I picked up a 905R (9.5) with the stock V2 stiff shaft (lighter than the tour version) last year. I hit it fine, but my spin is also in the 4k range.

Thanks,

Two shafts with equal frequency and kick points will produce different spin rates. Heavier shafts will produce lower ball flights and spin rates than lighter ones. Many "tour" weight shafts feel bad to many players because they are stiff and heavy. To lower spin rates you can make the shaft stiffer or heavier or both.

Also make sure you creating true launch angle with your driver. If you do not have enough loft and you have to create it, you can see some high spin numbers, check the side spin numbers to verify.

This is the 'straight skinny' from one who knows. Please, no threadjack responses here, but go to http://www.lynnblakegolf.com/forum/s...0260#post40260 and post regarding Jeff's accomplishment today!

Listening to the Video where Brian tests which ball to use, some questions arises.

With his driver, his stats are 13-14 launch, around 2800 spin and around 150-155 in ballspeed.

Is this optimal?
Which distance will this produce?
What loft/shafteweight/flex does he use?
Hitting the ball before low point"should" produce more spin......or not? and how does that comply with the above stats?

JEFF!!! where are you man?

Check this out. I believe that these are optimal numbers for a given clubhead speed.
