The Aldila Cannon came out in 1976 and the Tony Trabert C-6 in 1978, or possibly a little later. Here's a photo of them together - you'll note the similarities, though the C-6 is a little bit longer. There's also the Slazenger Phantom - Kuebler lists it as coming out in 1974, but this racquet didn't hang around long, because it tended to break easily. Luckily I was able to find one in pretty sound condition here in New Zealand and at the bargain price of less than US$2! This has to be one of the most beautiful graphite racquets Slazenger produced. See how well the grip matches the graphics - I had it put on after I bought it. I haven't played with any of these racquets yet - has anyone here tried them out?
