Slow play set on a dangerous flop?

Hello,

This is a Party Poker $30 + $3 NL Texas Hold'em game. Blinds are $15/$30.

After the flop, the 2 mini-bets made me suspet that at least one of my opponents is on a draw.

I was tempted to call thinking that it is my best chance to grow the pot and maybe even make a bundle (example: Qh on the turn). But on the other hand, I don't like to let the other 2 guys get a cheap turn card that might bust my set.

Comments?

Thanks!
