Take a look at this random link from the web: http://www.ellic-sport.com/tennis.html I recently obtained one midsize version (85-90 head from the looks of it) of the "Pro One" supermid shown in the upper left of the link. Looks and feels like an amazing "player's" racquet, but I know nothing about it. Boxy flatbeam profile that's at most 17-18 mm thick (PS 85-like). Glossy paint. Braided graphite and kevlar. Weighs 12.7 oz. strung with a leather grip and synth overgrip. It says "Pro One" on both sides at 12 o'clock, and "Midsize" on both sides at 6 o'clock. I've seen this racquet version in a "Supermidsize" before, but never a "Midsize". I also have a few "Rusedski Pro" supermids, but they're different frames. Even the "Pro Ones" that resulted from and after Agassi's time with Donnay, I thought, were only MP and OS, never just Mid. Long story short, did a little wall hitting yesterday, comparing it to my nCode Tour 90s, and without getting into any string/tension issues, this mystery Donnay feels incredible, like a hybrid of a Prestige Pro (flex, forgiveness) and a PS 85 (firm, low-to-the-ground, solid feel). Actually, I will mention one string issue: the strings currently in this nasty Donnay are no-name and feel quite loose, and it still plays like it was born from jets - a real, fresh stringjob will only make it better. Can anyone shed some light on this midsize frame? From what I've pieced together (some of you guys have helped with this, no doubt), this thin-beam "Pro One" series was a continuation of the "Pro One" model brand Donnay created for Agassi back in 1989, and this red-white-blue cosmetic was the version that existed back when Donnay signed Rusedski around 1999. Rusedski's PS 6.1 95 were then paint-jobbed to look like this already existing Donnay "Pro One" series. Donnay then carried over the "Pro One" cosmetic into the new Rusedski line cosmetic, rather than creating a wholly new colorway for their poster boy Greg. The "Rusedski Pro" properly customized can be made to bear a close resemblance to Greg's original PS 6.1 95. However, none of the Rusedski series sold to the public came close to matching the "Pro One" series specs, particularly in beam width and static weight. Sound right? Thanks in advance.
