playing a mix of levels

[Fiasco]

So ive been playing a mix of 25NL 50NL and 100NL recently (even though Im rolled for max tables at 100NL) because I cant find enough "quality" games to play @ the 100NL level. Should I just bite the bullet and resign myself to the fact that Im going to need to be playing in games with less than 35% to the flop?

Anybody else play a mix of levels like this? Anybody know a good reason why I shouldnt?

PS
Back when I used to play other games (LHE, PLO8, whatever) I used to do the same thing.
