Suggestions for Vegas Mid-stakes?

[Hyperrrprank]

Heading to Vegas for the first time since my conversion to a serious poker player. Any recommendations or suggestions on where to play mid-stakes? I'm most interested in where the opposition is juiciest, but ideas on comfort or style are also welcome.

I've played as high as 20/40 at Commerce and Hawaiian Gardens in Southern California, and plan on playing at that level in Vegas.
