I think you will like it, @OB. I thought I was "connected" on my Powershells before, but the Reflex is even more connected. I'm finding that, as mentioned above, finding the right setting on the straps is important. I'm snug on the bottom, tight on the center, and the upper is just connected loosely just enough to keep it from coming out. I fine that the bottom of my foot is planted firmly, but the loose cuff allows my ankle to pivot just enough in every direction to keep me freed up.
Like you, I was on the Powershells, and have used double high wraps since I was 13. Not having the feel of a binding on my rear ankle was strange when I went to the R-Style. I'm sure I could get used to it, but I just sewed a drysuit strap to one of my intuitions, and it still feels like I'm wearing a boot.
Next spring, I want to try a RTP...
