tR,
I'm with dub. Don't be afraid to wheel that sucker. When I went to my first Zoo I was going to do a ride along, but got convinced to go in my baby and had a blast. Todd is an excellent trail leader and very patient with people who have never gone before. On one obstacle he almost literally held my hand as I went down it. I am still SUPER crazy careful with my VX on the trail (and I'm stock height) so you could hang on my six and be just fine. Besides, it sounds like Todd is picking a relatively mild trail for the VX only run.
