My friend had a pair of masterminds a couple years back that he destroyed in a little over a season. He was light, did not go out that much, and did not do anything crazy on rails (he only did beginner features for the most part).
From what I've seen and heard the masterminds are ok for the light skier who wants twin tips but doesn't really fuck with the park or is a beginner park skier. However, they are not durable whatsoever.
