So I've been using a g402 for over 5 years now, and it's starting to show a little wear, so I've naturally been looking for an upgrade.

The g402 is pretty heavy at 144g, and I'm constantly hearing about how light mice are the future and how aiming is so much easier, so naturally I've been looking for a lighter mouse (70-90 grams). The only issue is after looking through all 40 mice in rocketjumpninja's top mice website, and watching hours of people ranking and reviewing gaming mice, I can't seem to find a single mouse which is both light, and also has 3-5 side mouse buttons.

After getting used to having those side buttons, and my productivity my gaming basically relying on those hotkeys, I'd much prefer to not have to downgrade to only 2 side buttons, and so my conundrum is this:

Are there any good mice with 3-5 side mouse buttons, that are also noticeably lighter than my relatively heavy 144g current mouse?
