I use a 2 or 3 foot Monster cable. Was pretty expensive, but it still works fine and for 16 ohms or 8 ohms, I better not be getting any tone loss (you only get tone loss if the impedance of the cable drops below the impedance being carried over it. Having a cable with much lower impedance gains you nothing).
However my Monster patch cable died pretty fast on me... and I wouldn't ever pay that much for another cable again when I can get Dimarzios for less than half the price which are every bit as good.
However, I would avoid planet waves because they oversize their cables a little bit and they can get stuck in jacks or bend your jacks.
