I play the 11s (but mixing it up with the 33s more and more) and the daytime is a rock garden. I played 10 or so SNGs yesterday afternoon and we would still have 7-8 players left at Level 6 (and this is at the 11s!!). At night, we are often down to 4 or 5 players by Level 3. I played a few 33s last night and we were at the bubble by Level 4 or 5.

p.s. not sure why i don't try the 22s. the 33s are just so fishy it's not worth bothering i guess
