Well Joe, most of my notes on these came from what you,
@retrowagen and
@vsbabolat et al posted here in the past. In any case, I doubt that I can say anything about a single racquet with wood in it that you didn't already know like the back of your hand!
@rodracquet is the only one who can tell Jerry whether the Golden Ace hypothesis is supported by physical evidence, since he has an actual example on hand to examine (1 of only 5 made, per his opening post), though Retro had already pointed out in post #9 that at a minimum, the grips are not set up the same way on the two models in question.
However, it is a virtual given that Kunnan Lo made the W90, as by then he was the only contractor making racquets for Prince, regardless of frame composition.
