there's one other downside to a one-wire and that is no remote voltage sense. I don't know if that's an issue for you but in my car ('55 Stude with Stude engine) there's about 12 feet of 8 AWG (or more!) between the alternator and the battery cable. The wire runs from the back of the alt. on the pass. side of the car all the way around the engine compartment into the pass. compartment and to the ammeter, then back to the starter solenoid where it meets the battery cable. I just like the three wire because it provides for remote voltage sensing; I can compensate for voltage drop over that long wire run (and with a lot of accessories on, it can be significant.)
Now if your alt. is mounted on the driver's side and you don't have an ammeter, you probably don't need that feature...
