£25NL (if anyone else plays it) - at full ring, there is 1 good player, 2 or 3 decent players, 2 or 3 players who aren't appalling, and 2 or 3 complete fish. At 6 max, you'll normally be the tightest player on the table if you play 26/13 like I do, though maybe 1 or 2 of the others will be good players. Still a couple of pure fish per table.

Every 3rd or 4th table has too many decent players to be worthwhile, so watch for these and don't be too proud to move.
