Better mouse than Corsair M65 RGB?

[UnholyCarcass]

I find that the M65 is a bit too heavy for me even with the weights removed. I was looking into getting the mionix castor. Those who own that mouse, how has your experience been so far? Is it lighter than the M65?

What about the specs? Googling says the Caster is 141g and M65 115g in its lightest configuration without adjustable weights.
