I'll cold call a 4bb raise with any PP from 55-JJ. If there are other callers I'll call with suited connectors, 65s-JTs. The tighter the raiser the better IMO, I want to be up against AA/KK as often as possible and get paid off when he can't let go of his over-pair, which is practically always at lower limits.
My actual rule* is that as long as the raise is <5% of my or my opponents stack (whoever is smallest) it's an auto-call with a PP; if it's >10% it's an auto-fold. Anything between is a judgement call.
I never call with weak Aces, suited or not. Usually I'll only call with AK, AQ if the raiser has very loose standards.
Obviously you prefer to close the betting but unless I have a reason to belive I'll get a re-raise behind me I don't mind not being last to act.
I would guess I am TAG, with a vpip of 21.81 and PFA of 2.64... possibly sLAG... but that's just not a very nice abbrevation

* Not my rule originally, I read it in Pot & No Limit by Bob Ciaffone.
