Any ideas on the best way to provide a thermal break when using steel studs?
The structure is in Charlotte, NC. The wall assembly is curently drawn as 4" metal studs with Icynene insulation, 7/16" OSB fastened directly to the studs, 2 layers of felt and siding.

Doug,
The thermal bridging through steel studs is so great that it's a waste of time to insulate between steel studs.
Install rigid insulation on the exterior of the OSB — the thicker, the better. Of course, at a bare minimum, you'll have to meet the minimum R-values required by your local code.

Yes,
Do NOT use Steel Studs unless you plan to use 100% Outsulation.
Doug,
