The North swivel works well when you manually turn it. The Naish one is up on the lines and often doesn't work.. no manufacturer has ever had a swivel up there that has worked reliably. Personally I just do back or front rolls to untwist my front lines so it doesn't matter to me.. I would rather they just left it off their bar system (in fact they have omitted it on their 2013 Ride bar).
but you can just turn the line under the swivel? I am very little attention to it, I think mine works (not sure)...
Hmm..but I know for sure that I can just turn the lines...so turn the lines under the swivel to uncork the line twists above..Once the twists are under the swivel the tension is enough to then if the line under the swivel is twisted, just turn it back super easy...presto no twists...but this is when the swivel is almost ground stuck (last years bar).
