I just bought an Estusa Boris Becker ProVantech RB (Roundbody) Championship Limited Edition racket. I am looking for specifications for this racket. I would appreciate if someone can provide specs info. or any kind of info. for this racket. I have been looking all over and not able to find any info. The only thing I was able to find out was that this racket was that it was made around 1991. The racket beam, cross section, etc. are all rounded. Very nice design. Beam width is very classic at 19mm. There's printing on the throat -"Computer Assisted Design Limited Production Handlaid Graphite Fibers". Any info. is appreciated. Thanks.
