I am have signed up for a Ski Mountaineering course to take my advanced resort skills into the backcountry. I am looking for a starter bc ski that will not break the bank. I have found two used pairs at this point that I would like to get some advice on. I am 6'1" and about 220 lbs, usually ski a 188. The first pair I found is a 2011 Black Diamond Justice 188 that has been mounted with Tele bindings so I would have to buy new bindings. The second pair is a 08/09 Black Diamond Megawatt 178 including Marker Duke bindings. I know the megawatts would be a little short but I figured it would cut some weight in the backcountry. Feedback on which one would be best for me would be great as well as how much to offer for each.
