Yeah, 3.5% pfr is really low. I open raise KQ & AJ from all positions and raise them behind limpers (but my FR pfr is 14%). If they're suited I'll usually call raises with them (occasionally re-raise), if offsuit I'm almost never calling raises, except from loose pfr'ers.

Since you're obv a bit more conservative, I'd recommend dumping them offsuit in EP, open-raising in MP and later, and always raising both from LP. If they're suited you could open limp or limp behind limpers in EP & MP, and still always raise in LP.
