If you're going to try opening your ranges up a bit, start doing it in late position and work your way back. Also if your going to open UTG I'd rather raise than call. You give away any fold equity you'd have from a raise if you just call.

EP ranges should be nitty and you don't need to add in SC's for balance at $2NL because no one pays attention to what you open with and theres quite a few stations so good luck repping a big hand postflop when you completely miss. Good luck repping a big hand without initiative either, although I see it worked out for you this *one time.

FWIW nits bring home the bacon in microstakes games.
