Just get a Sensei Fnatic edition or something if you want rubber. Then remover the sticker around the sensor if you have issues. As for any acceleration I see none and if there is accel, then you can disable it through the drivers via ExactAccel. I myself played higher than most in competitive CS and know several ESEA-Invite players.
It doesn't matter what the mouse is. Good players adjust and adapt to it. However, the Sensei is an amazing mouse. Then only complaints were longevity, but I figured out a solution for the majority of sensor issues. It's fixed several mice including mine. Simply remove the sticker around the sensor on the bottom. It is probably collecting dust and messing with the sensor.
This mouse tracks amazing. Custom LoD. I have complete control of this mouse.
Settings if needed: 1600 dpi/899 dpi, steelseries axactaccel,aim,freemove: 0, 1000Hz polling rate.
Let it be known, my cousin got the standard Sensei and the mouse wheel has a lot of resistance, while my Fnatic edition is a lot less resistant.
