I've never ridden the Raidens
The Rome's are nice
But I went with the Uprise
Basically the Uprise has just about every cool feature from every other binding on the market, all rolled into one.
Super soft ankle strap like the rome 390, the ankle strap holds to the side like rome bindings, toe ramp, blablabla and this weird suction cup thing that actually holds your boot into the binding.... I actually don't like it and I'm about to make it not work anymore.
The auto strap system takes some getting used to but once you got it, it's pretty convenient.
The uprise is a mid flex type of binding that you can do anything with... Pretty close to what my Union Force flex was, maybe a tiny bit softer.
Really the Targa and Uprise are packed full of really sweet options, and you can't go wrong with either. I can't speak on a Raiden except they don't have much of a name
