Sand Devil's are a cheap tire, and you get what you pay for. 99% of the people here when you ask them what is the best Sand tire, they will tell you Skat-Trak. BansheeDan used my 10pdl skat-trak's and loved them. He's also around 120lbs. Might want to PM him about his set-up. For dirt I use Holeshot XCR's and I get good hook-up. I've also heard good things about cut knarly's.
