I picked up a used set of skis off Craigslist a few weeks ago. I tuned them last night and took them out on the local ski hill for a few hours. They are the same length as my other set (160cm), and virtually the same width at all measurement points.
I did notice they seem to be more flexible than my other set. They also don't appear to be as thick where the bindings mount.
Can somebody explain to me why (or if) ski flex matters?
I am going to Colorado in a few weeks and wanted a backup set. I am not experienced enough to really "feel" major differences in how they ski, so I am kind of lost here.
