Well you brought a good point there. You personally didn't like the weight. This is one of those parts of a computer setup that really no one can answer for you. It depends on how you play, what kind of weight you like, shape, etc... I love my G502 while my wife hates it because of how low it is. You need to go to a local shop (Microcenter, Fry's, Best Buy) assuming you are here in the US and just trying as many mouses as you can. Or just buy them from Amazon use it for a week and if you don't like it return it. (Or buy all three and return the two you don't like) But it will depend all on how you use a mouse in order to find the mouse that is good for you.
Hope I made sense.
