I figure if one hand is on one end of the cue, and one hand is on the other, where the bp is probably won't make a huge difference
but I don't know for sure, and am curious. say if more weight is in back, could that affect a player's stroke in any way?
would that affect stroke speed or anything else? what if the cue is more balanced towards its center? etc.
Very interesting question, and I'm curious if there's anyone who can describe a good experience.
From my personal experience I want to add that it is relevant to consider also abolute weights, not only balance points. From my personl point of view / my personal senses, cues feel very different while stroking, and having two cues with same entire balance point does nothing mean about playability or performance of a cue.
Diving deeply into this topic one quickly understands that weights and balance points for all three "units" - shaft, butt, entire cue - have to be considered and analysed if you want to find out good answers to the original question.
But still if you have 2 different cues that have exactly same "unit"-weights and -balance points, even if cues are exactly same in these 3 main "units", they will probably feel different with different performance. If you include also the taper + diameters of the shaft and butt aditionally, the chance is much higher that you will endup in cues that might behave very similar.
But let's have a look at one of the common cases: Changing the weight of a butt by adding or changing weight bolts, and nothing more: All cues that I owed so far had their unique setting that meet my personal expectations at a relative maximum, which means that I can feel comfortable in principle with each cue by find the rigth weight setting of the butt. But this only affects the feeling - if I feel good while stroking, or if there's anything is not feeling the right way. Over all years of playing different cues and shafts, I feel mostly comfortable if the cue is not too heavy. Having a cue below 20 oz and the right weight setting allows me to use my wrist in a way that I feel very well. As heavier a cue was in the past, as less comfortable I felt regarding the wrist action, and I never had a cue over 20 oz where I felt good, but there were much much more cues below 20 oz, within a total rang of 18-20 oz that were OK to me. My actual 2 playing cues (2 butts and 2 shafts for each) feel in all 4 variations perfect to me, and the entire weight is between 551 and 557 gr. (which is only a difference of 0,2 oz), all 4 variations have the same entire balance point, but if you compare the shafts' and butt's weights and balance points the differences are bigger. Some of the shafts have added weight at the joint-area of the shaft which also strongly affects the balance point of the shaft.
The final pure feeling that expresses in "hit" and sound" of the cue while stroking and also the overall performance of a cue is also strongly depending on contruction and material details. Which means finally to me, that if balance points and weights are the same, it is not sure that you will like all there cues although they show same specs for weights and balance points. Coming back to my introduction sentence, I'm very curious if anyone can share specific information and experience and how deep this information will be.
