I would like to get a mouse that has more buttons for playing MWO. Currently I have a Logitech G500. I have narrowed my choices down to three: Logitech G600, Razer Naga, and Razer Naga Hex. The only problem is, I've never used a Razer mouse before and I heard they are a little on the smaller side. I went to Best Buy to look but they don't have demo units for the gaming hardware. I don't have big hands but I do have long fingers. Any advice?
