As a strictly tournament player, I've been thinking about trying ring games a bit, but I really have no idea on the bankroll requirements, what levels to play at etc etc. I have some newb questions regarding this subject.

For example, when someone says they are playing 400nl referring to ring games, what are the blinds at this level? I feel so stupid asking this

I am going to deposit like 300 to 400 in two days on my stars account, and I was thinking of mixing it up with ring and my usual sngs, is this a good idea or should I just stick to what I know?
