I have seen this before on a few aeropro drives and in particular David Nalbandian's pog longbodies that he used to play with. Is this a certain racquet technicians custom butt-caps? http://www.rolandgarros.com/en_FR/news/photos/index.html Are these soft like volkl's replacements by any chance? 2 of my frames have broken butt caps, so I just wanted to check these out. Regards, edit: sorry that I am computer illiterate.. I am trying to post a pic of the butt cap, but I guess I'll just describe it. They are yellow and have a large red "SC" (I believe). It is in the photo gallery for the last day of the qualifiying. The player's name is Juan Pablo Guzman.
