Anyone using a Wavetrac FWD diff?

I've got a Golf GTI Edition 30 with the boost increased from the stock 0.9bar, to 1.4 bar. The resultant pain to balance the pleasure is the original clutch (86K old) now slips from 3 - 4K rpms. Oh and a TC system that can no longer cope in the first 3 gears.

So I'm considering taking the opportunity to stick a diff in it whilst the trans is off. I've had a Quaife in the past and wasn't overly impressed. If one axle is unloaded, it's still an open diff. I've read the Wavetrac is different and doesn't send all the torque to the unloaded wheel. Can anyone confirm / deny?

Has anyone tried both and have a preference?

Alternatively, is there anything better the usual ATB suspects that is every day usable on the road?

I suppose an ATB + the factory TC is the best of both worlds because wouldn't the TC brake the spinning axle, therefore allowing the diff to shunt the power over?

Wavetrac claim their's is a hybrid plate / ATB system, which locks the two axles together in no load conditions, or so it seems to imply here at least - http://www.wavetrac.net/technical.htm

Sounds interesting!

A full plate diff would be too much of a compromise in a road car, from what I've read. Ranging from awkward low speed manners (along with interesting noises) to annual maintenance and adjustments.
