Ronix Binding Help - One vs RXT

I’ve been out of the wakeboarding world for quite a while... My Ronix Cell bindings disintegrated when I tried to ride last. I bought a new board (Ronix Camber 144) since none of the new bindings would fit my old Ibex..

I’m looking at the 2020 Ronix One or RXT bindings, but I can’t find any comparable differences between the two (other than appearance). Can anyone tell me what the difference is? Any pros or cons to either?

I’m also open to other suggestions for bindings if you have any.

Thanks!
