Yeah, pretty much what Jupit3r said...

I was an 18/10 when i played at these levels and that seemd to work fine. UTG I would guess you ought to be something like 11/8 depending how tight/loose the games you play at are - I like to raise low pairs from here in tight games and limp them in looser games.

You seem to be calling preflop raises with too wide a range for my liking at these levels - Without a read on the villain and if the stacks weren't really big I would limit myself to pairs and AQ/AK - this should keep you out of trouble post flop and help to bring that W$@SD up over 50%.
