Haven't bagged a driver a 2 years went to GG yesterday spent 2.5 hours hitting every driver for 2015 and walked away with the Z+ with the stock stiff shaft spin was around 2500 rpm with the weight forward carry distance of 250 with total average distance of 265. Needless to say I went home with it as it gave me the tightest dispersion of all the drivers I hit. I saw that they are offering free shaft upgrades with this club and I wanted to get see if anyone else has hit this club with alternate shafts besides the stock Matrix VLCT ST Graphite?
