When I picked pool back up in 1993 at age 44, I started with a standard shaft (McDermott).
Since then, I have spent some time playing with an old "cat" 314 shaft, an original OB shaft, a Z2 shaft... and now I am pretty much back to standard shafts.
The best shaft for drawing whitey back was the OB shaft. Don't ask me to explain that... it just did... and that was with the standard tip.
Today, I switch back and forth between a Timeless Timber shafted Bob Frey SP cue and a Z2 shafted Bob Frey 4-pointer cue... and a third cue (Dave Jones custom) that I just took receipt of that has standard shafts with it. I'm focusing on shooting with that cue right now.
I don't plan on going back to any of the OB shafts and Predator shafts other than occasionally playing a couple of games here and there with my Z2 shafted Bob Frey.
