I've always liked the Rival series, the shape is quite unique and good... wide back, thin front, seems to work well for aim and comfort. The smaller 310 along with the upgrades to the sensor, cable and other features and now going at a very low price when on sale, makes it a very attractive option. One thing to note: There have been many reports of the side grips falling off. Most people just glue them back on, from what I hear. There are some minor build quality concerns, but overall it's quite good. I'm hoping my sample copies aren't as good as the retail ones... time will tell. Medium large, large mouse, be sure to check the hand size guide to get an idea of if it's suited to you.
