My track is hardpack clay with a light dust covering on it. Usually pretty dry and slick. What would be better to run, the high torque clutch basket or a pinned top shaft (yielding full time 4wd)? I'm thinking I should run the clutch basket without the pinned top shaft. If the top shaft is locked it would mean all four wheels could slip whereas the clutch basket would send power to the wheels with traction. However if the power is evenly distributed to all four wheels all the time it may be better.

Suggestions? Also, what kind of tire should I run for those conditions?
