see The Volkl Grand Slam was a contemporary of the Highspeed 35 but for a different target player. The head size is smaller but the beam height is about the same except at the very top which is slimmer than the Highspeed 35.
seego to site The color, red and maroon, is very nice and very German/Austrian. The cosmetic is very aggressive and well ahead of it’s time. Typical of that era the cosmetic finishing is very, very minimal.
