Hardened pinions are absolutely fine from my experience. My CRT .5 runs an 18t against the stock 46t spur, and the motor has even shifted, killing the gear mesh (audibly), and the pinion is still fine.

My Savage with a KB45 10XL and 10s2p A123 (20 cells total) runs an Ofna center diff with steel spur, and hardened 20t pinion. This setup has enough power to MELT a Kyosho plastic spur, with perfect gear mesh. And by melt, the teeth of the spur don't strip. And the hardened pinion takes the abuse no problem.
