Most challenging was an old Völkl model - a yellow beast with a black plastic/nylon throat that was strung somewhere in the 1970's poundage range - up around the 70's or so. I'm pretty sure it predated any of the Servo Soft models.
Hard as a brick and rocket launcher to boot. Truly a "players" racquet if ever there was one - I sure as hell wasn't good enough to control the ball with it.
I had some of the yellow with black nylon throat Völkl "Worldcup" MS 24 mids in the mid-1980's... sounds like it could be the same frame? Sylvia Hanika, Karl-Uwe Steeb (before he got on the Fischer Team) and Wojtek Fibak (among other Euro-Pros and US Pro Mark Dickson) used this model in the mid-1980's. Any rate, they were heavy, stiff, poorly balanced, slow through the air, and impossible to string to a point where the ball feel, power, and control could be even remotely compromised. I smashed one out of pure frustration and gave the others to my then girlfriend. Shortly after, she gave up the sport!
I still have the Völkl 1985/86 catalog which I was given with the frames. In looking at it, Völkl printed
one single recommended string tension for mains and for crosses for each of their models - not a range! - as their frames were so sensitive to precise string tension. I had never seen anything like it before, or since. The newer Völkls are much better pieces of equipment, country of origin notwithstanding.
If it was the MS 24, it was from the same mold as the venerable Servo Soft, which Völkl produced for many years there in Germany, before the shipped production offshore to China and began their newer generations of frames (coinciding with the Petr Korda era)...
