FK1-B WHITE V2

You'd notice a difference. Would you play better because of the weight? Probably not. It still feels better though imo. I think wired to wireless would be a bigger quality of life difference than the weight, especially if you're a lower sens player that does arm swipes.

Something with the shape of the fk1 if you can’t find a fk1

fk1 comes to mind with your handsize, i have slightly bigger hands and use the fk2-dw perfectly aswell though, so you may want to consider that too! ”Ergo for claw grip” is pretty much FK in a nutshell, can recommend.

Zowie has this grip coined as "carpal stabilized claw" which I think is a very correct description, at least for me. I tend to contact the base of my palm so the mouse is anchored there and then regular relaxed claw. They recommend FK from their lineup for it which fits me like a glowe. 

For work/non-gaming I really enjoyed the G305. Portable, comfortable and you don't have to worry about recharging or whatever. For gaming I am currently on the Superlight, which is probably my perfect shape. I really like the FK1/FK2 too
