Can anybody tell me the difference in the two Predators shafts. Really looking for info on the tapers. I have shot with a Predator 5k2 with a 314-2 for a couple of years. I like the taper of the 314-2 but not the soft hit. The shaft will be going onto a Schon R-7 I just got. I like the hit with the stock Schon shaft with stock tip. I know i don't like the taper of Predator Z shafts. Thanks for any help Michael
