Does anyone know what the first part to fail would be in the 4-stage P60? Is it worth upgrading to the steel ring gear, or would something else go first? I'm wondering if the steel ring gear would keep it alive a little beyond 35 ft-lbs.

I don't yet have any first-hand experience with these gearboxes.

In 2008 a 256:1 BB Gearbox failed on us (which I believe was the 2nd generation, the P60 is the third). We unknowingly ran it for a couple of seconds after it failed, but when we took it apart we had stripped almost all of the ring gear teeth on the final stage.
