Can anyone verify the XRC is in fact 100% fiberglass? I've been looking for vintage Head advertisements stating the frame specs but so far have not located any. Perhaps VSBabolat will come to the rescue on this! Also, is the racquet hollow or is it a solid piece of fiberglass (assuming the material is, in fact, 100% fiberglass)? Does anyone have nice clear pics of the innards? I would never consider sacrificing a usable XRC... However, If I could locate a broken XRC, I'd perform an autopsy to learn how Head created one of the most plush feeling frames ever produced. IMO, the XRC should be updated by Head. I'd like to see a modern XRC, using the same materials (100% fiberglass), a similar headshape of 93-95 sq. in. with specs in the range of 13 oz. and 6-7 points HL (strung). I believe that to be a pipe dream... but it sounds like one sweet racquet!
