Thanks for this post. Honestly I don't know any of the above. I have a fairly large hand, but not THAT big. Regarding mouse weight, have no idea what I like or should aim for. Or switches. etc. Like I said, I'm no professional gamer and I'm sure they would obsess over these details. I'm just someone that wants something better than your bog standard desktop mouse, hence I thought the Corsair Katar would be nice. It looks good, gets fairly good reviews and isn't too expensive, plus it will work for right handers and left handers. Definitely not wanting advice on a best mouse as that is probably wayyyyy too subjective, but rather if people have any experience with the mice that I'm looking at or within a similar price bracket. I get that anything in my price bracket isn't going to be world class, just looking for personal experience if possible.
