Heard the setup briefly at RMAF. Sounded pretty good from what I could tell.
He's got an interesting point with the golf ball. As he said at RMAF, they're actually very precicely made and very uniform - if they weren't they'd wobble or worse off the tee. Probably a fair bit of analysis/experimentation to get the balancing act figured out, but once done it probably eliminates a fair bit of relatively expensive machining.
Is the bearing another evolution of the oddball Well Tempered bearing? I still have a WTT bearing shaft burried somewhere in my junk pile, from a friend that used to be a WTT dealer. I had intended to experiment with the idea, but never got around to it.
