it is all a matter of personal preference. If you are changing cues more than your underwear lol, then a ld shaft would give you the same feel and confidence in your shots everytime. Over the past few weeks I have "test-drove" a predator 314-2, OB1, OB2, and a predator z2. I have owned a few ob1's and ob2's. My personal favorite is the ob1 because of how it feels for me. to me a predator doesnt give me the same feel, but that is just my preference. Try to get some playing time (more than a few shots, more like a few hours each) with each shaft and come up with your determination.
