Bernie, Thanks for the great explanation. Have you tried this alignment on woods, too? Can you give any insight into the physics behind this alignment?
Spine alignment is a funny thing, I think. When I first signed up to these lists and was doing my research, it seemed that Spine at 12 o'clock was the way to go. Then not too long ago, NBP at the target was the way to go (and certainly felt better in the clubs I've tried it on. I wonder what's going to follow NBP-COG... ;-) -Dave On Sat, October 4, 2003 at 5:04 pm, Bernie Baymiller sent the following > > Yup, same clubs.
