33s vs 55s

[runner4life7]

I think this has been discussed a lot, so feel free to ignore. I've just began playing the 33s, (i.e about 50) but I plan to play about 250/week so I should hit the "500" mark within a couple weeks. If i can beat the 33s easily which I think I can and I am not judging from my sample size but more from the 22s and I like to believe I'm decent, should I move up to the 55s? On avg. will a winner at the 33s make more per game at the 55s? Is 50x the buyin sufficient at the 55s? I think thats it for now...
