UTG is a nit with VP/PFR of about 9/5, over about 50 hands, no reads on the other two besides stack size and their propensity to limp

Considering my position I think this is a good time to isolate/pick up dead money. UTG limper's range consists mainly of 22-99 (maybe 22-88) plus a KQs, though that's unlikely, since I have him as a nit, or he may be the type to limp AK, though, PFR of 5 is still semi wide.

When I raise, Against 22-99, I am fairly happy if he folds or if he calls, cause he will be easy to play against. The other two are prob fisher and have broad way and other sub TT type pocket hands. I would prefer my hand to be suited but this, I think is a good opportunity. Now, the question is on sizing, which I tend to go with 3x from bu + 1bb per limper, thus a raise of .30 is in order.

How many just fold this pre? How is my reasoning for isolating here?
