Is this really that big a deal?...
A buddy of mine who just got back into the game (hes really been bit by the bug this time) and is all for this process and even built a shaft puring device for himself. Im just trying to avoid tearing apart all my clubs to pure the shafts and also dont particularly like seeing the lettering on my driver and 3 wood graphite shafts if thats the way puring shows their alignment should be.
on some occasions, it can make a difference, mainly with woods, but overall, not really. i have one because i like to tinker and i know that if a ball goes left ot right, it's definitely not the shaft being out of alignment.
The Puring of shafts has become somewhat obsolete now as shaft technology advances every day. Shafts are becoming more and more stable, and the "spine" does not affect the club in nearly the same fashion as it used to. Take for example the new Taylormade ReAx Shaft. The shaft is reenforced through the length of the shaft to prevent ovaling and to prevent the spine from taking a different bend at a ball. Bottom line is, unless you have a very, very repeatable swing, you would not notice a difference anyways.
I think puring is a big deal, espiecaly if your looking to break into scratch from 1-3 handicap. My 3 wood was tested for the FLO and was found to be at 90* from where it was supposed to be. Now I hit some great shots with my 3 wood, but then some that felt great would be pushed left or right. I am not sure if that had anythign to do with it, but it should be back next week and I will find out if the change helped or not.
most of the time, shaft puring wouldn't be notice by the average golfer, but there are times when it can make a big difference. iron (steel) shafts are the least noticed because they don't flex as much, but graghite can be a different story. i've had woods that i (13hc)and even pros couldn't stop drawing (and not a little draw either), pured the shaft (spined aligned) and the draw stopped. what shaft puring does is makes the shaft flex properly and consistantly by identifying the weakest side and strongest side of the shaft so that the clubmaker can position it properly when installing.
