I think your PF raise is fine. 5xBB is a decent size you don't want to be increasing your bet size just because of the hand you hold that will become easily exploitable as you move up.

His flop bet is less then half-pot I think I would have made a bigger reraise closer to the 40-50 cents range. If you get called or reraised at that point I would have to either put the guy on some AQ, KQ, QJ or some sort of flush draw. Like clairvoyantX said this is coming from a 5NL player so would love to hear other thoughts.
