To me, a roller can be in any maneuver. Any segment of a line or radius. I didn't mean a rolling circle.

Adding another class is a band aid. There are temporary advantages, sure. You might as well get rid of advanced if we add expert. It's almost extinct now let's not forget. Fix why masters is huge and advanced may be larger, and so may fai, while masters may shrink.

Just my 1/2 cent..
