I'm using Razer Mamba since 6+ years from now. I know it's not fully quailfied for your needs, but it's a superior mouse, specially if you like the shape of the DeathAdder.
Also you don't have to use the Synapse 2.0, you can use the older drivers too:

However Mamba is NOT cheap, but it's worth it if you want a quality/smart mouse for the next 4-5 years.
