Umm....the only Ai 98 (11.5, 322 SW--the one being asked about by the OP) is the lime green one.
Play with what you want to play with. I play with Ivanovic's old racquet....which, as far as I know with, no male pros ever endorsed. But to call it a girly stick is laughable (even if it is blue-ish purple and lime green.) You should see my friends who use Pure Drives and the like trying to play with it. It is considerably more demanding than their rocket launchers. They are stifled by the need to actually swing the racquet.
I demoed the Ai 98 last week, as I normally do with new Yonex frames. I thought it was an improvement on the Xi 98. The headshape was pretty similar to my RQIS, and it wasn't as clunky-feeling as the Xi 98. Better weight distribution, in my opinion. Not quite impressive enough to switch, but the best Yonex I've demoed since my stick.
