For me to be willing to fold this I've got to see villain as capable of check-calling a higher set on the turn and I don't think many do this so I'm happy to put more money in.
I also think we should be raising the flop a lot.
We cant raise this flop alot, we have the one valid hand to do so, alot of the time we will not...........
don't think we should ever be raising the flop after cold calling really.
