My thoughts were one of the main contributing factor is not properly warming up the engine to operating temps before being driven hard.

Didn't know that by rarely driving it hard enough could also lead to the RB wear. Could you kindly explain how this could happen?
Thing is, I occasionally drive my ///M and hardly drive them hard, just a few spririted drives.
By driven hard I mean don't be afraid to let the engine spin out to redline. The mechanical components are stable at 8k rpms and you're not adding any additional stress that the engineers didn't already think of. So go ahead and enjoy the S65's soundtrack often.

Leave it in second gear when making the climb. 2500 rpms is too low in the rpm band in my opinion. If my current cruise speed and gear is at 3k, I dont' upshift. Once I clear 4k with normal driving I upshift. When I'm driving aggressively, 6k is a norm. All once fully up to temp. When I can and the cops are vacant I try to hit 8k for fun. ;-)
