I met Earl a few months back and did a clinic with him. His cue is a mess. The shaft is close to 15mm diameter, and he has tape around the butt, an extension that stays on all the time, and a tennis racket looking grip over the butt end. It's quite the contraption. But he can play.
I thought it was funny how the pool world has moved to less/no deflection and slimmer more advanced cues, and Earl is still rocking out with his beat up old Jalopy. Also we are in South Florida and it's extremely wet down here, he dragged an armor all dashboard wipe all over the table to "slick" it up. But man, he was such a great guy. Don't listen to all the rumors, he was great, informative, and a pretty funny guy
