A Rarity …Continued
It is fun to have these fairly rare racquets to work on and get back into playing condition! We will report on each of them as we go through the setup procedure, and note any differences that we find.
We will try to compare some of the specifications to current or “recently current” racquets to see how far we have come…or not!
