There are more skiis to try than people willing to let you try, if that makes sense. I would get that length figured out, but I would say 64-65 max. Some old and tried blanks will not let you down, but will still leave you wanting more. The Concept is all over the place and cheap cheap cheap so you can buy with out feeling like oh man this is going to have to be it. Have seen a ton of New Radar Senates on Ebay for cheap also. My buddy just got a Senate C which is the carbon version. Will be a faster ski. But if you are truely serious about skiing look at D3, and Goode or the Obrien Strada. They will cost you some money but you will be fitted with a ski that is for you and will make you a better skier very quickly. Unfortunately your talking like 10 times the money of the above mentioned skiis and I'm not joking.
