50nl FTP - Reraised pot, but he checks behind flop?

[Freelancer]

Some reasons why I limp;
1) Your always OOP, this is a BIG downside
2) If you limp you have direct odds to hit your set
3) Your usually in trouble if anybody decides to call preflop.

Reasons to raise;
1) You believe that its very likely to take it down preflop because villain has a tendency to limp/fold.
2) You think that there's a high chance villain will play fit or fold with better small PP's (big+).


Basically I need a decent read to raise here and my default is to limp.

Did I miss anything?
