Would it make any sense to divide up a 250 class into weight categories to keep things fair? By weight...I mean rider weight without gear. You could run a fatty class (which I would be a part of) and a girly boy class. I imagine 140-200 covers most of the MRA with a few exceptions. You could do a minus 170 class and a plus 170 class. It would not be too hard to have a scale handy at pre-tech or something. Just an idea.
