Ability is only part of the equation. The best skier on the mountain on the wrong size ski will not be happy. Actually, I have heard similar complaints from others similar to your height weight dimensions who did't like longer Bones. People think because they are an excellent skier, they should always be on a longer ski. Wrong. You pick the ski brand for your ability level, your level of aggressiveness and what you plan to do with it. You pick ski size according to your body dimensions. I don' ski 187 Bones because I didn't like the way they demoed. They weren't suitable for my body dimensions. So be it.
I guess we will just have to agree to disagree. If I was skiing on 187's I'd say for sure they are too big but the 180's were right in my wheelhouse. And btw I also skiied the 173 and though they were more easy to turn I ski didn't like the feel of the ski so maybe I just don't like the Bonafides. Trust me I really wanted to I just didn't. Why can't someone not like a particular brand of ski's and that be the end of it? Why do some people feel they need to defend the ski they use to the bitter end? If someone told me Line skis sucked and didn't care for them I wouldn't tell them they were skiing the wrong size. I would chalk it up to they don't like the skis. My buddy ski's on Blizzard Bodacious' and tells me I should ski a real ski like his. I just laugh and enjoy myself. Fanboys are amazing.
