I really like Chadwick. I wish it had a little more variation other than just rocks, rocks, and more rocks. That place would be amazing if it had a track because then you get the best of both worlds. I ride a yz250 (that's really set up for more mx and xc and not wooded out, besides the bark busters) and get along just fine but you definitely need good throttle and clutch control. A buddy of mine had a KDX200 out there last time and really did well on it just because its' suspension is so soft and it has very controllable power.
