I'm having a hard time deciding between these 2 mouses, and I know the only difference between them is their sizes, but I can't exactly test them out at a local store. And I would say I have medium sized hands so that makes it that much more difficult for me to decide. I need your guy's opinions and experiences.
As a reference, I own a Logitech G9, steelseries ikari, and a Microsoft intellimouse 3.0. I have also briefly used a razer deathadder and a logitech MX518.
