I have a POSH Mini-switch on mine. Ordered from WebBike Japan for $60ish including three day shipping from Japan. Come by and play with it if you'd like. Those racing switches are also pretty cool tho. If I had bumped into those I might've gone that direction.
Couple things:
Get an "All Balls" bearing kit for the front-end swap -- They even have a calculator tool for which kit to buy on their site.

Renthal Inner Diameter is different than all other handlebars. If you want bar-end accessories this is a no-go. If you want to run both bar-end signals and mirrors off the shelf you'll have to go for an Oberon setup ($$$$$).
Also, holy fuck you're fast.
