A 56-inch cue stick with a 19 inch balance point will feel/play very differently from a cue that has a semi-permanent extender to get to 62 inches but also has a 19 inch balance point. If you want to report the distance from the butt, it will help the OP if you also include the total length of the cue stick.In my world as a cue merchant, the balance point is measured from the base of the cue buttcap. It's personal preference but I expect cues I receive to balance in the 18-1/2 to 20-1/2" range. There are too few people in the marketplace to accept a back heavy custom cue (below 18" baance) or a pronounced forward balanced cue (at 21" or more). As a player I prefer in the 18-3/4-19-1/2" balance range. I do find that I prefer a more forward balance with a heavier cue (for me 19.4 to 19.7 oz.). Just like shaft type and size, tip type, cue length and girth--these are all personal preference variables.
I think the specification of balance point from the bumper originated at a time when nearly all cues were within an inch of 57 inches long.
