Sorry for the bump but what the hell, i don't look on this site much.

18 tables is quite a lot but by the time you're ITM you're lucky to be in half of them so playing push/fold with high blinds it's not too bad. The worst stage is probably about level 3 when I'm still in most of them (tight early statergy).

I've had nice results from 18 tabling, makes the bad beats easier to take too since you don't get time to notice.

But yeah 18 isn't too out there, there are quite a few people doing 25-30 though i've no idea how you'd manage that.... maybe one day.
