i like Predator Z shafts, i use that shaft for 3 cushion, Mike Massey turned me on to that idea. I have played with the G core shaft and it wasnt for me, I like the predator better. I like stiff shafts for 3C not pool. I have a Schuler 3C cue that's stiff as they come, its great, its over 30 years old and cost me $140 for the whole cue shipped.
