I've been looking at this myself, how big are your hands?I loved my deathadder but my left button died so after some time i`m now with g502 so far i really like it

Logitech g305 would be my suggestion. Maybe too small u suppose but that is a good thing for claw grip so worth a look. It is light and the wireless is perfect. Plus single battery lasts months, used mine every day for at least 2-4 hours since june and still going strong.
