Not that I'm an expert but...
the sngs (20 and 50 points) usually suck, just like a free roll lot's o people trying to get lucky and often succeeding. It depends how many points we are talking about, the best bang for you buck is to find a sat to tourney u want to play in, and be patient enough to see when there is one with only a few people registered. less of a field makes it easier to win and since its always the same amount of seats the prize pool is not affected. oh yes, don't waste your points on the poker after dark, just sat in from a freeroll.
