My friend just went to a local thrift store and found a Wilson Prostaff midsize with cover for only $3.99. The buttcap is white, with a red "W". The letters under the "W" appear to be "JWO". It doesn't have a bumperguard. I've looked up the info for such a raquet, and even though there is a lot of info on the Wilson ProStaff, I cannot find anything on this one in particular. I have a St. Vincent and a made in Taiwan Prostaff, but I know nothing about the info on my friend's Prostaff. Does anyone here have any info on this racquet? Thanks!
