The loss of traction, power delivery and acceleration is total and instantaneous
when the diffs are open. The advantage when running locked in auto-x with sufficient
power is major and unmistakable, I think on the order of 1+ sec on a long course,
an absolute eternity in auto-x.

I always run center locked in the rain/sno/ice on non-ABS qs. The extra stability
is very real, just use good judgment about your speed for the conditions at hand.
If ABS is an option I run open as the advantages of ABS outweigh the additional
stability [this is very subjective and I expect that others will have a very different
opinion on this point]. I never run at any kind of speed with center and rear locked
due to the potential nastiness of locking the complete drivetrain at speed under
