Looking for a mouse with certain features, does it exist?

So I'm currently using a Razer viper, love it! However... I want 6 side buttons, I tried using Razer Hypershift but couldn't get on with it.

Features I want are,
Lightweight
6 side buttons
Wireless
Small (viper size)
Palm grip

I seen Razer do the Nage Pro but it's just too heavy and big.
Is there any other options out there?
