So I tried out the Steam 105. It felt like a toy compared to the Vortex. It just didn't feel solid. What came to mind as I hit with it was that it felt hollow, kind of like a shell of a racket without everything else. It did have a lot of spin, but not as much as the Vortex. I could play with it if I had to, but I don't think I could ever grow to like it. No wonder so may Steams are showing up on the For Sale forum.
I used to change rackets every 6 months or so. In June it will be 3 years since I switched to Vortex. I don't see myself changing any time soon. I am looking forward to trying the new Pro 116 to see how it compares to the prototype that I have.
