The X8 is made for palming. You could use a claw grip too.I've already got a sidewinder X6 keyboard, so the X8 would fit in nicely.. any idea how the size/shape compares to an MX518? I'm a lazy gamer, I palm the mouse with my whole hand.
Compared to a mx518 its less round, but similar style of holding and there is also a rest so your pinkie doesnt drag.
