I went ahead and cut the track yesterday and rode a few laps.
Will look for some advice from Rick when you get there, I think I have a tendency to cut the technical sections a little too tight which ends up with tires shredding the surface prematurely. Might be beneficial to open it up more into more free flowing design rather than point & shoot dirtbike switchbacks.
Also cut a mini track for mini bikes and a small straight (think runway) for straight line drills.
As you can see in the pic, I had a problem dipping my head in the turns. When this happens, one often ends up on their head. Rewiring my brain from RR was the biggest obstacle for me. Constant reminders to myself while riding helped a great deal. Great coaches combined with chasing bionic and jet didn't hurt either.
