I already use Tail casings.I was disappointed going to carbon wheels couldn't tell the difference it was only once I changed to much lighter tyres knocking off almost 1kg that it made a notable difference (went from DH casing to trail tyres). What was very noticeable was the higher engaging hub on technical climbs much better so worth it for that but if I was to do it again I'd stick with DT Swiss aluminium FR rims.
It's just one of those things I've wanted to try for a long time I need to get it out of my system.
My 481 will become my DH wheels.
