Cue questions

Well sure there is a difference. The balance is going to be different when some of the weight is focused into a small area vs. spread over the full length. What works best for you is what you like, which could be one as easily as the other.

I mean.... Yeah it matters but there are so many variables you couldn't make rules about it. Obviously a weight bolt moves balance point rearward, but of course that doesn't mean every cue with a weight bolt will be more rear balanced than every cue without. Choice of materials/construction methods/taper are all factors here.
