I recently saw someone had a predator z2 shaft and that out didn't have the short and ugly 3 inch taper. It looks like there is a huge difference between these shafts. I switched to a 314-2 shaft 4 or 5 years ago and it seems to me that the is little room for error in your stroke that is costly on long shots. I'm looking for more information before I spent the money on another experiment.
