I agree about the mices, I've used all the dethadder mices, my hands are not that big and I'm planning to try the EC2-A.
By the way the new deathadder elite disappointed me, the build quality is pretty low for the price imo.
The QCK+ Heavy feels too thick for me tho, I prefer the standard version. Recently I tried the razer gigantus but the mousepad had wrinkles issues, I had to return it (a lot of people had this problem). Lately I feel like razer's product quality is going down.
