Southpoint will not tolerate spreads more than 1-2 or 1-3
And even that might be pushing it at higher limit games. They basically want people who, if they spread at all, do so very slowly over a very long period of time or basically just parlay 1x or 2x per shuffle. Spreads of 1-4 or 1-6, even betting red chips, is not tolerated. It's just the way they are.
That said, Southpoint is a considered a pretty good comp house so if you give them 45 to 90 minutes of black action (FLAT BETTING) or some short sessions of intense VP play you'll get good offers in the mail and their hotel is a nice place to stay (even though it's out of the way).
