Well, this was an old school poolroom in the 70's, and there were some very talented players who shot there on a daily basis. Lots of big money games went down there. And I don't recall them having any problem with masse shots or jump shots.Yes, and usually those places didn't allow masse shots or jump shots either. I recall a few places in NY that did that for awhile too. It was all about the house preserving it's equipment and not about the players. Usually the break cue balls were cheap balls that were not of the same weight and composition of the object balls, and that little patch was like a launching pad. Any kind of decent player hated playing in a place that required those things.
