As the title states, I do play good with the shaft but it has a bit of a wobble in the center of the shaft, basically if I roll it on my table the distance between the center of the shaft and my table changes as I roll the cue. It's not a huge gap difference but I can feel it when I stroke the cue. I brought it back to seyberts and they straightened it once but it's back and I don't like it. Spending $260 on a shaft and it's not perfectly straight gets in my head. I want to love the shaft, it's what I wanted but having it not be perfect just isn't settling with me. I'm sure I can drive back to seyberts and they can straighten it again but how long before it comes back?? I replaced the g core with the predator but I'm having second thoughts. I am thinking about trying a ob2 or an I3. I liked the G core I just wanted to get a thinner better shaft. A friend has an ob1 and I like the hit, but I was thinking maybe a more advanced mcdermott shaft might have the feel I like. I guess my confidence in the Z2 is not there because if the wobble in the middle and making me want to change it out while I still can. Please any advice or thoughts would be appreciated. Like I said I want to love the predator shaft but I am afraid can never permanently get rid of the Issue it has and I will never have 100% confidence in it.
