There are 4 casinos in that market if you count Casino Windsor. Motor City, has 6 deckers and allows RSA. If you have the patience of Christ, you can attempt to play there. I think they have a really crappy DD game, too.
Main floor tables at the other 3 are 8 deckers (No RSA, No Surrender DAS) and CSM's. The best pen for the 8 deckers is at Greektown last time I checked. This is consistent with CBJN, too.
All places in this market close tables the second the crowd thins, so wonging in doesn't really fly. However, I've wonged out and in just sitting there all evening saying: "I'm just sitting this one out" with no better excuse than that, at the 10-120 level, and I've never had a problem.
Also table minimums jump to $25 bucks on peak times with all the tables full. I think the MGM keeps some 15 ones open all the time. Don't go to any of these places on a weekend night, you'll be wasting your time.
High limit room at MGM has 6 decks with about 1.75 behind the plastic. I have no info on the high limit areas of the other two stateside places.
The High limit room at Windsor is probably the best game. Six decks with about 1.5 cut out. If you are staked for a $20 min. bet or higher, go in the wee hours and find a $25(Can.$) table. If you find an empty $50 table they'll often drop it to 25 for you. Beware the currency conversion. %4 goes away if you convert U.S. to Can. then back again. You might need to play for a few hours before your EV earns the exchange rate.
