I'm desperately trying to find the perfect mouse. I have rather hands with long fingers...above the norm for sure. Sometimes people comment about how long my fingers are. I might have hidden alien genes.

As long as I can remember I've always used Logitech mice. For the past 5 years or so I've been using the MX5xx series starting from the MX500,MX510 and MX518. It has been tolerable but sometimes I get bad cramps in my fingers. Also what pisses me off the most is that my ring finger rests on the lower right curve. It isn't really comfortable. I move my mouse with my fingertips, with my hand resting on the desk.

I bought a Razer Deathadder a week ago and I can't describe how much I hated it. It was worst than the MX500 series from Logitech for me at least. The grip was awfull and the extra wide buttons WTF? They felt way too mushy and disturbing. They call those buttons non slip? I never felt something so slippery. A real joke.

I was thinking about buying a Razer Diamondback 3G but with my experience with the Deathadder I'm not sure anymore. I really want a mouse with 2 side buttons on the left side but I guess I could settle for 1...

I've read the 2007 mice benchmark but I fear it wasn't too helpful.
Also some mice like the MX300 and G1 are almost impossible to find.

Please note that I game at 1920 x 1200

Any help would be greatly appreciated.
