I largely agree those might be seen as benefits to some.
But none are really playability benefits. I get that some Pro's may like them as well as some beginners but what is a beginner comparing it to? The Pro likes it for the radial consistency? I thought they could run 400 balls with a broom stick.
I am simply saying the pool world AT-LARGE, from a playing perspective, especially new players, probably only benefit from the cool, latest and greatest factor. And apparently, they can leave them in their trunks weeks at a time in Texas. A huge benefit.
Personally I would encourage any new players to begin with a good maple shaft. I think the feel of wood teaches more and if you want to move to CF in time after you actually know how to stroke, feel free. I don't have anything against them, I'll just never buy one. Just like I don't need a glove.
