I've been using a SteelSeries QcK Heavy for a long time, and picked up the Zowie G-SR mousepad this week after hearing how good it is, and how it actually lays flat. I also had to get a new mouse, so coming from a Deathadder 2013, I got the DeathAdder Chroma.

Immediately I noticed my Lift Off Distance about doubled, and I thought it was just the mouse, until I tested it on my Zowie EC1-A, with the QcK Heavy and G-SR side by side. Is there any reason that the LoD increases on the Zowie G-SR? I'd like to avoid using Razer Synapse's 'Surface Calibration', since it makes the mouse feel a bit off.
