I use Hydra's now.
The teflon isn't ideal in that it is rather stiff and only likes specific bends, the good news is that it's small enough to be very easy to thread in tight spaces and the stiffness has allowed me to turn the right angles directly up in the configutation aiding in the slack prevention for an accedental pull on the cable below.
A compromise to be sure but I think they're a great addition to the Warmer AKG and WarmMod Oade Sound, adds back a touch of speed and air.
