I wouldn't buy the Holograms without demo'ing first. I think they're gonna be a love it or hate it thing.
I'm not a big fan of Ride and their aluminum baseplates, but if you already have a pair of Rides and like them, the Maestros should match the Cobra pretty well.
One binding you don't have listed that I'd throw into the mix is the Flux TT30.
