Split Handles

Perhaps its a model C difference but I'm not sure what you're referring to and didn't notice any problems the shackle might hit

No, not a Model C difference. From your posted photo the chain swivel connector appears to be about 10" forward of the handgrips. With the stock handle the handgrips are up much closer to the swivel connector. Your set-up is fine if you have that forward clearance to the uprights at the catch, but for those with a longer reach the swivel connector and shackle will end up between the uprights holding the PM. For those users it would be like threading a needle on every stroke. In that case the fix I described is required.

Elbows down does keep the wrist straighter but doesn't keep my wrists from popping. Split handles it completely goes away and there is no choice but for the only forces on the wrist to be a straight pull

Absolutely. Hands, wrists, and forearms in alignment with the direction of applied force. Your set-up (and mine) ensure this. The C2 stock handle doesn't. It is a design deficiency.

Ah I've got plenty of space left at catch. This is actually as far forward as it goes with my butt on the seat and a hand on the handle
