Reads: limper is 57/15 loose passive recreational player, btn iso'er is reg with 50% open OTB

Question: Cold call or 3b ?

Thoughts: Raising leaves a SPR of around 3.5, assuming the limper folds. I also believe that opponent will put me on a lot of AAxx combos so it will get a bit tricky on a ton of flops. CC'ing leaves me in poor position post flop with a hand that has good hot and cold equity but doesn't have much playability.

I am leaning towards 3b'ing and stacking off on a lot of flops (when it goes HU with the btn).
