I'm sure this is 101 question, but I don't know the answer so gonna ask it anyhoo...

Assuming 1) Playing 10NL FR, 2) playing relatively tag (12/10-ish) and 3) picking the loosest tables I can find on FT... VPIP >30...

Where my usual PFR with mid+ PPs is 4x + limper, and I'm finding I'm still ending up MW on the flop... should I keep increasing my PFR amount (esp. w/ TT+) until I get to mostly HU? Vice versa on tables that tighten up and my 4x is consistently only taking the blinds. Should I drop it until I'm picking up a caller?

Understand positionally dependent, and my main issue is w/ AA, KK, AK where I want a caller vs. lower PPs where I'd rather just shut it down pre-flop.
