yeah i claw grip thats the prob so my hand needs to lie further back
What do you mean claw grip? You cover the whole mouse with your hand? Or the opposite?
I have two Razer Mamba's for my PC's. Tom's had the discount listed. They were like 80$ a peice after all said and done. Anyway, the deathadder is the same exact size of the mamba. Before the mamba i had a logitech MX518,a logitech G5, and currently for my laptop i have the G700. The G5 and G500 i believe are the same as well.
To me, logitech mice contour nicely to your hands. Since your hands are not large, most logitech gaming mice are not be the way to go.
I found some sizes on a few examples. They should be correct, for the most part
Mamba/Death Adder - 5(L) x 2.75(w) x 1.67(h)
Abyssus 4.5(L) x 2.48(w) x 1.57(H)
mx518 9.5(L) x 9.5(W) x 2.5(H)
g500 8.7(L) x 8.1(W) x 3(H)
After using the G5 for two years, the cord twisted out. When i received my mamba's they were more slender compared to the G5.
Your decision on the Abyssus is a good choice if you dont "claw grip".
I hope this helps, good luck!
