John, how is the Prince O3 tinkering going? I personally have decided to abandon experiments on them. Didn't seem important anymore. Also, if I were to perfect their performance for players then it still wouldn't be usable because not even the best paint job can disguise those O-ports!
I am still curious about your findings though. Did you find the humerus weighting concept along with hoop manipulation to be effective on the O3s?
