I’ve gotta say, I like this so far, nice review!. I’m going to have to try it out. Gaming mice are such a personal decision it really takes buying more than one till you get it right, despite good reviews like yours.
I have big hands that almost nothing feels good in. I’ve tried the G-skill M780, but it has no comfortable place for anything beyond the adjustable rear palm.
The Patriot V560 looks good: nice and wide, and finger molds for pinky and ring fingers. To use those though, my hand sits at an unnatural direction, with the thumb being pinched between the heavily sculpted top of the cushion, and the dpi selector along the base.
I’ve settled on a long term test between the Mionix NAOS 7000 and the Coolermaster Sentinel III. Two different designs, but both ergonomically comfortable for large palm grip, which is important with carpal tunnel.
This Rival 600 looks to be a similar size and shape to the Sentinel III, which is why I’ve got to try. It seems most mouse manufacturers are of the mind that small sized people are the only gamers.
