I want to buy a performance shaft for my cue. Between a Predator 314, Universal Smart Shaft, and OB-1 Shaft. Which one do you think is the best? I have hit with both the Smart shaft and the 314 shaft. I have to say the quality and hit of the smart shaft was very impressive and I liked it better than the 314; then again the 314 has been aroud for a long time with many praises. How do you guys like the OB-1 shaft? What are your opinions?
