Need advice - binding upgrade for freerider.
 

So I've been riding for about 3 years now and last year I bought the NS Lotus which I am completely in love with. It's smooth and charges the mountain perfectly. I am pretty much freeride. I don't go in the park, I just like to charge the mountain with control. I am trying to get into backcountry but it's unlikely until I graduate uni and move myself to BC for the rest of my life.
Getting back on track here, as I said I have a NS Lotus 149' and 2007 Flow Prima bindings. I'm looking to switch it up cause I want a pair of really good bindings that are going to last me and do what I want. I have never had an issue with my Flows so naturally I'm leaning a little toward the 2013 Prima's. Mainly I'm just looking for suggestions on great, responsive freeride bindings. I use 7.5 boots.
Since I got my Flows when I was a beginner and haven't looked into bindings at all since then I really don't know much about which brand provides nice responsive bindings. I will take all suggestions into account! Heres what I have so far:
Flow Prima
Rome Strut

I use Ride CAD. This is one of most stiff binders on the market.
Here's the list of another one:
Nidecker act carbon (pro 900)
Ride Spi (highback aint that stiff as CAD)
Burton C60.
Catek FR2 (deserves to check out, but don't buy this - they'd kill your lotus).
may be something else, i don't know.

I'm personaly very happy with canting base on my CADs(i got two pairs btw). this was on NRC also. This is the greatest thing about the bindings.
