rolled for the $50's now. too fast?

[dboy23]

well I have 20 buyins for the 50's. I'm playing the 20's right now. I'm trying to decide if I should keep playing 20's, start playing 30's, or jump into the 50's.

I'm pretty confident at the 20's, and am sure I can beat the higher levels. I've only played about 90 20's though. My BR is growing faster than my skill.

So I guess my question is how much harder are the 50's than the 20's. Also should I bother with 30's or just skip them?

Thanks for the help.
