09 SS Recoil compared to 08 ronix one

So I have been back and fourth on the Ronix One since it came out and I am thinking about giving the flex a shot this summer. Just wanted to know from people who have ridden them how they compare. I am looking at getting an 09 recoil 142 or an 09 ronix one. I have not ridden the ronix one since it has been slightly modified and made more predictable. I consider myself to be an intermediate rider and ride most of the time wakes that are not very beefy. Oh and I have ridden the 08 response on cable but without fins and it was very fun to tail press all around just never ridden flex behind the boat.
