For a stupid reason I bricked my Corsair M95 last night. I loved my M95_RIP. Just got back from BestBuy with the Nightsword and will soon be setting it up. I like heavy mice. Spent my life as a carpenter. I have the Corsair K70 keyboard and know what you mean about the software. I recently had to relearn iQue when I wanted to change my keyboard layout for getting back into playing Fallout 4. I'm kind of liking the idea of the large sniper button, which the M95 lacked. If need be, I'll superglue a rubber pad to the sniper button to make it more usable.
To bad the program is a shit show, especially after the update needs a tutorial... they made it unnecessarily difficult as far as key binds. drag and drop keys to mouse key boom done other than macros.. like the old mad catz program.
