Errr...twenty years ago making graphite racquets was considered technology. Now it's all that Flexpoint, nCode, Liquidmetal, Aero Beam crap. Much of this stuff is just new marketing gimmick and the each of the major racquet companies seem to turn over a new set of flagship technology about every two years.
