I was in Vegas last August and December and I don't recall any SD 3/2 games on the strip. The SD games I did see/play at were at Tuscany (shuffles up after 3 rounds, after 2 if there's 3 or more spots played), the Silverton but also poor penetration with 10/11 doubling restrictions, the Hacienda outside of town where they shuffled after every round, and of course El Cortez downtown- pen was dealer dependent but generally anywhere from 50-60%. So besides El Cortez I'll usually play DD or shoe games.
