The answer to that depends entirely on what kind of combat you plan on flying.

I don't know where Canyon is, but there is actually a lot of combat in the north-TX area. The most common class there is SSC. There are a fair number of options for SSC planes.

But the best idea is usually to find someone else in your area who flys combat and seriously consider flying what they fly. That way, you can get help setting up the plane and getting the basics down.
