For me it's a tie. First would be Steve Mizerak at straight pool in his prime. I've been told by a road player from the 70's that he could make your long periods in the chair entertaining while he proceeded to run off 100 or so. Ideal setting would be at my local room, South Hills Golden Cue in Pittsburgh, where he often would do a weekend matchup with Hopkins, Sigel, and Jimmy Marino, the owner. Alternative would be Jackie Gleason in the "Hustler" setting. Word is he could play pretty decent without Willie doing the shooting. I'd even wear a suit for that one.
