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,
