Yes, raising the flop for info would have been the right thing to do. I mostly feared K4, K6, K7. At these levels I often see people calling PFRs with these kinds of hands. You can't rule anything out.

2nd hand: The vast majority of pots that I lose are to flushs and straights so I am very gun shy. And I was a tad on tilt from the previous laydown of As.

Anyway, thanks for the comments.
