I'm partial to the Connelly Concept...I ride a 66" but thinking 68 or 69 based upon ur height/weight. I've skied Radar Senate some as well. The Concept is really forgiving and I can course ski in rough conditions better than anything else I've ever ridden. The Concept is definitely a ski you can progress with into shortline. For me at least I've found the 34mph specific skis like the Senate dont feel as good.
