Finally figured out my Superquad Driver. There are 4 screws that are used to alter distribution of the weight to affect hight and spin imparted to the ball. I thought it was adjusting the relative weight of each. Ther's not documentation online or anything like that. I FINALLY figured out that two of the screws are weighted, and two are not. By choosing which two of the four cavities hold weighted screws and which don't control it - there's no adjusting the weight or center of gravity of each. I guess my days of fixing bikes drew in some personal bias.
Either way, it feels good to shave 3° of loft of my driver. It doesn't sound like much, but it does keep the ball lower - I tend to sky my drives.
