Looking for new mouse similar to the Zowie EC2-A

I currently use the Zowie EC2-A but I really hate the full rubber coating on it. After I use it for a while, the mouse's coating gets very sticky. I have cleaned it many times but the coating is still sticky. It's at the point where i have to wash my hands after I stop using my computer because my hands feel sticky.

Is there any mouse similar in shape and size that has a different coating? It's for FPS games like CS:GO.

EDIT: BTW my EC2-A is the old version with the old Zowie logo. Not sure if their is a different coating with the new version. If there is a way to clean the sticky coating off and avoid buying a new mouse, please tell.
