I have the Steam 99s and enjoy it very much. The only problem I have with it is that the swing weight doesn't seem to be around 333 grams, as stated by Tennis-Warehouse. It feels much lighter.
Maybe I'm so use to heavier racquets ( 11.9 ounces and higher ) or maybe it's the Basalt material but this racquet feels really light, holding it as well as swinging it. I've tried other racquets that are around 11.5 ounces but the Steam 99s still feels lighter than them.
It just doesn't have the plow-through I was hoping for.
Otherwise, everything else is spot on by other reviewers (the higher trajectory, the frame stiffness, the extra spin, etc.).
Does anyone have the same problem with the lack of plow-through?
