I'm a 4.0+ all court player who plays more doubles than singles. Western grip forehand with a lot of topspin, two-handed backhand & 1 handed backhand slice. Both hybrids easily generate lots of spin. The tour is heavier and hits a flatter shot. The Shark has the most power, the Hornet slightly less, and the Tour a lot less. The Shark had a tendency to hit long for me unless I tried to keep it in. The Hornet is incredibly quick at the net, partly because of the weight and balance, but I also think the O-ports really do reduce the wind drag on a quick stroke. This made the racquet feel great on poaches and quick overheads. The two hybrids have a bit of a trampoline feel to the shot, but I believe this is mainly the strings moving and not really the racquet. The shots seem to go where aimed in a predictable manner as long as spin is put on the ball. I had a hard time hitting a powerful shot with the hybrids, but I believe this is mainly because I hadn't figured out the timing of the racquets yet. The O-tour was easy to hit with a full hard swing, but seemed unpredictable unless I was taking a full swing. The O-tour is significantly heavier and slower to swing, which feels good from the baseline, but comparitively sluggish at the net. If I wasn't playing a lot of doubles (or getting older) I'd probably lean towards the O-tour. Both the Shark and Hornet feel like they add extra speed and spin to my serve. The O-tour feels like my old racquet and has no extra pop.
