I posted this on Dunes and Dune Machine as well.

Which sand tires would work best for all around riding in the sand on trails, hill climbing and hook up?

My son's ATV has a CVT transmission so it has less output than a standard shifting quad. I don't want something too agressive that it causes the quad to bog.

I've been considering the following tires:
GBC - Sand Sharks (these worked well on his old 125cc quad)
ITP - Sand Stars
STU - Sand Skate II
AMS - Sidewinder
Skat Trak - Edge
