How does it feel to be this dumb? Good?
PX12 jib will be fine. Any PX12 will be fine.
If you hate the PX heel, try to find a Rossi FKS 120. Same 3.5-12 DIN range, same toe piece, but older racestock turntable heel. It's a good binding. Heavier, but good.
It might be a sign that Look/Rossi are completely ditching the turntable heel for next year. No more FKS/P series bindings unless you know where to look.
