I'm currently running my RM100 through my oversized Mesa Boogie 4x12 loaded with Celestion Vintage 30's and through my Genz Benz G-Flex (George Lynch Series) 2x12 cabinet.
With these two cabs, the head sounds amazing! Even if I play through either one by themselves, both sounds are very unique and solid. Especially the Lynch model cab because of the ports on the bottom that add to the bottom end.
