Another part of the problem is the lack of return spring for each cable at the hub itself - each cable is dependent on the other for tension, so at each end of the gear range one cable has no tension and gets bunched up in those tight turns in the shifter. Have found that running outer a bit longer than normal and making sure the ferrules are really well pressed into the barrel adjusters helps wee bit (but not much!)
