i have two of these rackets. i first saw it available in the states
around 1991-92. there were two slightly differing versions, both
made in austria. the first one said "classic beam" on the hoop, the
second one said "constant beam-classic flex". i believe that the
first one was a bit more solid, stiffer. i own the second version.
testing them on the rdc yielded a stiffness of 62-63, weight of 12.2-12.3oz. i also ordered the full length green "clamp shell" bumper guard, such as you see on the red prestige. with this installed, the
frame weighed about 13 oz.
i have seen this frame used by muster(full bumper), mark koevermans, david wheaton, rosalyn fairbanks. from what i heard,
a lot of the other prestige players didn't take to this frame because of its stiffness.
i had the grip pallet changed recently. the old pallet was solid foam, all the way to the handle. the new ones are these hollow pallets that seem kinda cheap.
