I have tried the 8sp and found it smooth as silk, the weight was noticeable on lifting the bike only, the balance is way off with one fitted, though it was on a non suspended dale.
The great thing apart from bombproof built, was the fact you can change gear at a standstill. Came in handy around town, on the beach etc.
You could be in top gear, emergency stop, knock it down, then lat off up a hill of from traffic lights.
11sp is going down well with the fatbike groups in hard areas.
