I have an old racquet from my childhood. It's a Prince Ace Face 90. I wonder if any of you guys have the specs or have used it. It seems to look a lot like the Prince Graphite Pro 90 (i.e. Looks like the Prince Original but without the bar in the throat). 14 X 18 string pattern, 90" or 93" head size. Any idea what the stiffness rating is? It feels around 12 ounces/340 grams but I'm not sure (difficult to tell just by feel). I think it's made of Graphite + Fiberglass, but i could be wrong. Here are some photos I googled of an identical racquet to what I have (mine is without all the scratches). It has "Prince <T> Patented 1990 Prince MFG, Inc written on the inside of the throat. Any ideas? I have restrung it and have hit with it a bit. Very arm friendly in terms of shock absorption. Makes me want to check out the Prince Original 90".
