Yeah not to take away.... the QTII is a great system that can go almost anywhere.

I think one of the few areas that QDII will shine is steep slippery climbs where you don't want to slow momentum. Watching vids the main difference is you see the QTII videos slow down and even come to a complete stop before starting up again.

Other than that, its just more predictable when you're in a technical area with low traction. Its not really THAT much of a disadvantage. Throw a rear locker in and it'll be almost discernible
