Hi there I got a real kick reading all these threads.12-2 is rated for a 20 amp circuit. 10-2 for 30amp. The line will run cooler with 10-2 very very difficult to work with! Romex is national code, and refeers to the insulating jacket. Your
other code approved option would be THNN and conduit. More importantly than your wire options should be the service panel itself. Other than Square D QO line ,and another midwest company all panel companies do not use a solid copper buss bar! Good Luck!!
