Fold bottom set on nonscary board?

[haberdasher]

I can't find a WSEX HH converter so..

WSEX 8 handed $100 NL, Hero UTG w/22, 7 players in an unraised pot. I flop bottom set to a rainbow board and lead out with a two buck bet. Next player cold calls, player after that reraises to $9, folded to me.

Now here's the thing: reraiser is a 13.7% VPIP 3% PFR over many hands and my notes say "tite on flop too". I know this guy to be rockish. My main concern is that he's got me set over set. I just don't see him limping preflop with QQ, KK, AA after two limpers here, notwithstanding his low PFR%. And I don't see him going to $9 on the flop with a 77-99 overpair. Given the stack sizes (I started with 68 vs villan's 125) I felt I was risking my nearly entire stack to see the river weather I was up against a pair of 10s/Js, or paying maximum to see a larger set.

I think my call on the flop was a mistake. Thoughts?
