As for the shape I really like the Cooler Master Spawn because of this ring finger rest: There's no thumb or pinky rest, I hate them, they get in the way. Honestly though, it sounds like you might have to build a custom mouse to get everything or even half of what you want.
Check out this two OSTs (they're full game OSTs with loading and menu themes so skip tracks if you get bored): https://www.youtube.com/watch?v=X3CHn_EtAWg&list=PLwq4Nzvi5I172COXwejiKNvkfBgpK6ncz https://www.youtube.com/watch?v=qlkT5YUsrDE&list=PLwq4Nzvi5I15HU1Huhx1c-5wyrMR82wvL It's the A.I.M. series (aka Mechminds) about AI civilization of machines forsaken by their creators (humans), left on a terraformed planet to evolve and perfect themselves through planetary combat situations. You take the role of a mechanoid AI put into a glider - a battle hovercraft. It's a Privateer/Elite kind of game, with hovering instead of flying in space.
