Its a shame to see you throw in the towel, but i totally understand - i too work on my feet, and with my hands, so i need 95% mobility. I was bothered by what i witnessed in my FIRST intermediate race (30+ of us), but i chose to back off, let anyone pass me on the brakes, and mid corner, and sit in the back 10. I was amazing to see how people from out of town rode, just on the warmup lap, when they were gridded behind me - that was enuf to know that i should just treat it as a track day.
Its making me re-think next year when Race City closes - is it going to be the same positive experience as it is now? And as for WCC series, ill just opt out, or settle for 2nd last place (not that im fast enough for anything else - lol).
If you stil need a 'hand' fixin that beast - let me know, offer still stands.
