This past weekend I tried a driver that was backweighted - it was a demo driver from a company called "Tour Lock Pro." I seemed to have a noticeably tighter dispersion on the 8 to 10 drives I hit. They said it raises the balance point of the club, which helps accuracy, decreases spin, increases MOI, etc...(and does just about everything we want to improve our driving performance). Does anyone have any experience with back weighting to raise the balance point of a driver? Is there any science behind this or just the latest gimic...I know nothing about this, or this company, so any feedback would be great!
