Only played 2/5 NL before....Vegas -> play 1/2 or 2/5?

[boondockst]

My state (washington) only offers a 2/5 (100-200) game so that's the only I've played. I'm going to Vegas for the first time on Sunday and I'm not sure which game to play.

I'd prefer a more casual (read: soft) game but I don't mind the stake (2/5) so long as it's not too tough of a game. Add to that I've got a friend going with me who has NO live NL experience.

I haven't really seen this question asked before so I figured I'd throw it out there.

Edit: (Forgot to say, I'm only taking about $1000 so I'm thinking I should stick to the 1/2 since it is usually the same buy in as the game I'm used to, but If i run good the first few days...)
