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,

CG

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.
