Hi all,please forgive my ignorance but I have only recently discovered that clubs can in fact have a "SPINE".
Can you guys give me some info on it.
1...Where they are aligned in relation to c/face
2...How do the big producers in fact "find" the spine
3...Are they in all clubs
4...How important are they to the week-end golfer.

Any info would be grateful..Thanks again.
