You're starting a lot of threads of the same thing, it won't get you more responses so just bump up 1 thread. It might even deter people from responding and ignore you because you're flooding the main forum with the same thread over and over again.
Now as for why many haven't answered your post, if you did a search about this topic you would find that many believe the butt doesn't matter much when paired with a low deflection production shaft. Especially a predator shaft because they're hollow and don't give much feedback anyway.
Therefore a z-2 or 314-2 paired with any butt will still feel close to the same. The only thing different will be the weight and the balance point of the cue depending on which butt you choose.
Lastly, you can't go wrong with any butt, if you like that lucasi you have just buy a z-2 shaft to go on that. If you don't like that one then buy a new cue that fits you better and get a z-2 shaft to go with it. Either way the cue will play practically the same.
