This has been an interesting thread..
On the subject of diffs then, what's everyones preference.
1. Centre one-way (kit) - Medium off-power steering, medium on-power steering, easy to drive through bumps, pivots mid-corner on slippy surfaces. Rear wheel brakes only.
2. One-way diff - Lots of on-power steering, slightly more off-power steering than the centre one-way, doesn't pivot mid-corner, harder to drive through bumps. Rear wheel brakes only, usually the fastest.
3. Direct shaft kit - Least off-power steering, medium on-power steering, easy to drive through bumps, pivots mid-corner on slippy surfaces. All four wheels brake.

Of course if you run a one-way front diff and run a solid centre shaft you only need to buy one set of new diff balls!!!
