I really thought they had covered Fairway drivers with the Shock, Volt and Amp. I guess they need "straight" ones with the Resistor and Servo?
Anyway, Servo sounds like it has a lot more potential for me given the low power requirements.
I was throwing my Resistor along with a newish Firebird this weekend and they pretty much flew the same for me, so a bit too overstable for most lines I'm going for, but might come in handy for the extreme overstable slots as I progress, or when I go to windy courses.
