The White Star Twin is, or was, the ultimate performance racquet from Kneissl. In fact it looks a lot like the adidas racquet used by Ivan Lendl…
Like the Masters 30 this racquet was made in Austria and uses a bountiful amount of fiberglass included in the graphite matrix. The feel of this racquet is unique, for a composite racquet, and seems to be modeled after the most popular wooden racquets.
This racquet was from the mid 70’s I believe but there were many Kneissl racquets made well into the 80’s.
The head shape is based on the Kneissl concept of hitting the ball at the most powerful spot on the racquet, lower! So the racquet head is wider as it is closer to the shaft instead of larger toward the head of the racquet.
