I have narrowed my search for a hum cancelling strat bridge position pickup down to either a Fast Track 2 or a Super Distortion S.  I have a guitar with a Duncan Distortion in the bridge position and I love the tone.  The strat I am upgrading has a custom painted pickguard so I am limited to single coil sized pickups.  I will be using a Air Norton S in the neck position.  Any advice is appreciated, thanks.
