I think I'll stick with my diamondback as I prefer ths shape compared to the deathadder.
No lanbag included
I also think it depends on how you hold a mouse. Like do you have 1 finger over each button (all 3) or do you only have 2. Do you rest your hand/wrist on the mat and move the mouse mainly using your fingers, or do you have your hand off of the mat and totally elevated from causing any friction. etc etc
