That does not sound fair. Especially since he built the course for himself. I learned how to ride the pipe switch. So a course builder can race the same course. What if the course builder blames it on the other riders - says that they're just complaining and people get hurt.
Some courses are really good and that is because there are a few people putting input into it.
I just learned how to ride the how to ride the whole mountan switch. Erin Simmons I can ride some switch but probably not like you because you sound like you have become really confident in the pipe. I would never hire those people to work for me again. Jack Spinner Bx is on tv a lot. I need to think about that.
