What do you run? Rubber or poly?

Just curious what motor & trans mounts you use, Rubber or Poly?

Having once run polyurethane engine and transmissions mounts, I will now only run rubber. Polyurethane passes too many vibrations which is why the automotive manufacturers don't use it.

Did your poly mounts last longer then your rubber ones?

Longevity was never an issue for me. For example, I sure wouldn't replace my feather pillow with a wood block simply because the wood block would definitely outlast my feather pillow.

Not to mention, again, that rubber mounts typically outlast the vehicles the factory installs them into.

poly motor mounts here. Rubber wasn't an option when I upgraded my mounts, but to do it over again, I'd probably get Brown Dog rubber mounts with the added block brackets.

my rubber mounts were shot at 100K all of them, the trans mount was torn. and my jeep is still going.

Sounds like you don't like my 'go rubber' suggestion... go with whatever you want, sounds like you want to go with polyurethane. I'm just saying I used poly before and I'll never go back to it again.
