yes the ring would work too.
The hot and cool zones are a good idea depending on the thickness of your steaks.
When I do T bones or rib eyes I have them cut 1-1 1/4" thick. That gives me med rare on a 6 minute cook over rippin hot coals. (1 1/2 minutes flip, 1 1/2 minutes flip and rotate, 1 1/2 minutes flip again, final 1 1/2 minutes. off to rest for 3-5 minutes)
