Spike, You run a great show. I personally would not add another class unless you are going to do it based on equipment restrictions. My personal problem with offroad is usually over powered equipment. Most if not all the beginners show up with stuff they can't drive and have to dial it down, including me. I should still be running 17.5s in all my offroad stuff as it is a speed I have control over. No butt puckering corner speeds or ridiculous airborne acrobatics at high speeds. A full trigger pull isn't going to get me into huge trouble with limited power. But, that is my problem.

Keep up the good work, and don't let us rain on your parade!
