Message from my mentor!

I was planning on using my own bike to prove to the MM that I can handle my own bike in these excercises. This was the response I recieved....I think I should listen!!
You made the WRONG decision. LISTEN TO ME THIS TIME. USE THEIR BIKES. i KNOW WHAT i'M TALKING ABOUT. I'll say it again so it sinks in. USE THEIR BIKES.
Their course is set up for their bikes. They don't care if you drop their bikes. If you hit that wall, your on THEIR bike.
P.S. USE THEIR BIKESSSSSSSSSSSSSSSSS. are you getting the message?
