This race has been won by a full on DH bike every year since inception.naw, mass o' nuthin is really the perfect playground for a nimble 6" trailbike.
John P...it's full on fun! Top section is about linking rocks together (high speed ones that have something of a broken cinder block edge snuck in here and there. Definitely the tire choices Jeremy said...Comp 16's, High Rollers or DHFs.
Oh...and if want to sneak two bikes, there is some insanely fun, super long descent on the back side of the mountain that is a Super D race as well that is around 20+ minutes long with whoops and berms the length of it that I haven't gotten to ride.
