I guess that would be true if there was a larger difference in the two ratios, but it's not that big a difference.

Definitely will NOT help clearing gaps...from first hand experience...In fact unless you have a running start it will suck you right down in it.

That being said, I have tried all the combinations and think that the OD and UD together work the best for a sporty rig.
If youre only going to use one get the UD...The overdrive alone in the front tends to exaggerate the torque twist.

I disagree, I've been running overs in the front for a year and a half and the first thing I noticed was less torque twist. It shouldn't matter which way you go, in the end the front is over driven.
