I've been skiing on a pair of Plum Guides since spring, 2011 (so mine are one of the first imported into the USA, with ~70 days use on them), and I've been a big fan, due to the very high strength to weight ratio. However, about three weeks ago I had a heelpiece totally fail, which is disconcerting. I pulled out the skis to use and noticed that one heelpiece had an almost through-and-through crack in the metal, running more than halfway around the entire heelpiece, starting at one of the heelpins. I've heard of heelpin failures being frequent with the Plums, but I haven't heard of total heelpiece failure before, and I wonder about others' experiences? It's hard to imagine what could have caused solid metal to crack so dramatically; possibly very low temperatures? Plum is replacing them, but if I'd not noticed and skied hard on them in no-falls terrain, the result could have been catastrophic.
