my line here is call with any two if i feel my opponent is willing to raise with any 2. I'll take 3.5-1 headsup against a player who has a completely unknown range of hands.
My experience in the party 30 game is that alot of opponents are creatively agressive so if i hit the flop im leading out even with 72o paired 2s and 3 betting if he comes over the top.
