Hey Justin, I just got one of the original NEO's. I have been riding Connelly from the Prophecy all the way to the present DV8. I talked to Terry Winter about which size to get. I am also 5'8", 150 lbs and can run 35 50% of the time at 34mph. Terry is around our size and he rides a 65" and that was what he recommended to me. I got it this week and have only taken one set on it. Ran 3 28's, 6 32's and 4 at 35 out of the boat. Never missed a pass, so I would I have to say the ski is pretty good. It felt easier from side to side but still shut down, turned and felt stable. Hoping to get some more sets on it next week. I would reach out to Terry and talked with him, he is very helpful and will help you get it set up if you decide to try one.
