Vegas 5/10nl

[PokerFink]

I know this is a silly question and the answer is, "it depends," but in general how much of a step up is 5/10nl from 2/5nl? I've played lots of 1/2nl and a decent amount of 2/5nl and 5/5nl and I beat both comfortably.

Let me try phrasing it this way. Is the step up from 2/5nl to 5/10nl bigger or smaller than the step up from 1/2nl to 2/5nl?

Also, which vegas casinos regularly spread 5/10nl besides Bellagio? Which games are capped/uncapped?

Thanks.
