At 275 lbs, you will need the 800 and as much track as you can find in the Colorado dry powder. The goldfinger will bust the throttle thumb lever unexpectedly. The track will be ready for replacement after 4000 miles. All the bearings in the wheels, need to be replaced at 3000 miles. Consequently, You buy the 04 and I'll buy the 05 because it is a better sled by far. lol
