Becker played his late juniors career and early pro career (@'83-'84) with a familiar, collectable frame, the Adidas GTX Pro (yes, the Lendl frame).  Becker then had deals with Ellesse for clothes, and Adidas for racquets and shoes (he wore the blue and white Lendl Comps, as did most Adidas male players of that era).  Becker's tournament highlight during this period was a QF finish at the Dec. 1984 Aussie Open, which he played with the GTX Pro.  On paper, he probably could've gone still deeper in that event, since the Aussie Open attracted so-so fields then, and he lost to Ben Testerman (!) who just a half-year later Boris would've noshed on as a mid-afternoon snack, but I digress... .  Ion Tiriac, the brilliant tennis- and money-manager, convinced Boris that with his new-jack, hard-hitting, topspinning style, he needed a bigger racquetface to minimize off-center hits and increase his ball-striking error margin.  Remember, in early 1985, Boris was still just an up-and-comer, so it's not like Puma had to uncork the Deutsche Bank to sign him up (although Tiriac, the tennis equivalent of Scott Boras, probably inked a favorable deal for his latest protege).  Here's where it gets tricky.  Boris played his entire first Puma year, 1985, with a lower-tier Puma model, the G. Vilas.  Now, I know that Boris's model was modified more than even I know (see below); my point is that if you walked into a tennis shop say in Munich in 1985 that sold the Puma line, the G. Vilas was a cheaper graphite frame than the other graphites in the Puma line at the time, which were significantly structurely different from the G. Vilas because of their plastic throat pieces.  Puma was just getting into the racquet business, and Vilas was Puma's big signing splash, even though he was already in his career winter and had a penchant for moving from racquet company to company.  Vilas himself played with a higher-end Puma model, not his namesake.  (In 1986, Puma built a Vilas frame similar to the 1985 Colors series that Vilas used on tour, the teal/silver Vilas Power.)  The higher-end models then were the Colors series, 3-piece frames largely modeled after the Volkls of that era (Black Puma, Blue and Red) with differing graphite quantities.  The Colors series had the telescoping PCS handles.  However, the stock G. Vilas frame did not, featuring instead the cheaper discs PCS system with a fixed handle.  Of course, Boris's G. Vilas frames were all modified, and featured the telescoping PCS unavailable to the public.  In short, you cannot hope to find a true, Boris-modified, G. Vilas frame, because the version sold to the public was significantly different if only because of the lack of a telescoping handle.  However, every so often, you do see a beat-up G. Vilas frame come up for auction at a premium price because it was allegedly Boris's first Puma frame - as I said above, this statement is not really accurate.  By the fall of 1985, Boris was already using in competition close prototypes of the Becker Super (see, Becker/Lendl Wembley final Nov. 1985,  Becker/Schapers Aussie Open Dec. 1985, Becker at the Volvo Masters Jan. 1986).  For any Becker fans, you could tell it was a different frame because of the high-gloss red and navy paintjob, but these early Supers did not feature any writing on the frame, and featured a red, rather than the later white, throat collar.
