Bottom set multi-way, 8-max

[Phytopath]

How would you proceed in this multi-way unraised pot with bottom set? I know this is technically small stakes, but the players are brutal an more like NL25ish.

iPoker skin Nl100$

I have about 125$ in the BB, UTG has me covered and the rest of the table has between 65-100$. I have no real reads on UTG, seems like your average donk but I haven't seen him show down much he plays 35/5/1 over about 75 hands for what that is worth.

I get dealt The 3 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/spade.gif[/img] in the BB.

UTG player limps, 4 other limpers, the SB completes I check.

Pot is 7$ with 7 players still in.

SB checks to me, I bet out 6$, UTG immediately raises it to 18$, folded back around to me.

What is the best line here against your average donk? Re-raise AI, call and lead turn, re-raise to 50ish?
