I love my G602, but I also just don't care for the battery-powered wireless mice as much as re-chargeable mice. In my hunt for a new wired mouse to replace my Corsair Scimitar (which I love, but it has too many buttons for my use now) I've been testing out the G502 Hero, and its a great mouse - if you like narrower mice. While I like all of the features of it, it was just too narrow for me, and I wouldn't even say I have large hands. Its just a very sleek, slender type of mouse. But, the sensor is amazing and it has a tilt scroll wheel with free-scrolling capability and the ability to add weights to it is nice if that's your kinda thing. Without the weights, its only 121g, and it comes with 5 weights each weighing 3.6g. If you wanna stick with Logitech, then my best suggestion would be to find a store with some of the mice you're interested in on display and try them out to see how they feel. If you buy from somewhere with a generous return policy you can also take them home, try them out for a week or two and then make your decision. That's what I've started doing and it is much better than getting stuck with a mouse you end up not liking.
