Although I don't own a Crossbreed instructor belt, I wonder why you find a good stiff gun belt to be inadequate. I use really stiff horsehide belts and find them to be perfect for my needs. They aren't too thick, and they support the pistol, holster, extra magazine and other stuff I want on my belt just fine.
I make most of my own belts because I found a leather supply store where I occasionally get horsehide that has some untanned raw hide in the center of the leather. This incompletely tanned hide makes the rest of the hide feel as if there is a thin piece of kydex laminated into the leather. It is very stiff, yet thin, and unless I soak it in hot water, it is nearly impossible to cut with a razor knife.
The reason I like these belts is because they support everything without excess bulk. The instructor belt appears to have quite a bit of bulk to it.
Unless there is something your current belt fails to do adequately, why change it? (Don't fix it if it works, comes to mind)
