Voelkl made some attractive composite racquets, and had attractive eponymous lines of men’s and women’s clothing, shoes, and other accessories (bags) circa 1983-1986, and they even signed on as the official supplier of all of the above to the Soviet Davis and Federation Cup teams. The equipment was probably better than anything produced in the Soviet Union, but was sadly lacking performance to match the looks.
I believe they also sponsored a number of southern German pros (Hansjoerg Schwaier and Sylvia Hanika smong them) and, oddly, Mark Dickson (‘83 US Open Q’Finalist).
I was briefly courted by Voelkl as a junior in 1986, given some World Cup MS24 frames, and had a hit session with Sylvia Hanika (who was their marquee stalwart German pro and ambassador at the time). I couldn’t make the frames work for me; they were a little on the heavy side (I had been playing with the Kneissl White Star Pro Masters for a while, which was not a lightweight frame by any means, but didn’t feel like a shovel as the Voelkl did). The string bed also just had a dead feeling to it… not a cushioned, muted “dead” feel like the beforementioned Kneissl, but a hopeless, no power-and-can’t-find-any-sweetspot-whatsoever sort of weird feeling. I tried a few stringing solutions, but with no positive result. I gave up on the Voelkl and played for a season with the Max 200g, with which one could really crack a flat forehand, like that Kneissl.
