I realized that you might have already purchased your mouse, but I thought I'd help out with others who're reading this thread here. Someone here mentioned that CM mice aren't very reliable but they're really good actually. Just look at the ratings that they're getting on Amazon. It's pretty much on-par with Logitech and Razer's gaming mice.
With that said, CM's Storm Sentinel II and G700's wireless mouse are excellent options. If you ask me though, I'd go for Razer's DeathAdder for people who have larger hands. If you have small hands, Logitech G9x's laser mouse might be ideal for you. This
gaming mouse chart here should prove useful to anyone who wishes to make a detailed comparison before their purchases.
