In reply to frequent: I've been using the Vampires for 3 years now, use them in the twin front point mode, and find them to be a pretty good, stable, all-purpose crampon. The front points do wear, but not excessively - I'm nowhere near the point of replacing them. I wear them with a pair of Trango Evo Extremes, and find the toe clamp a bit fiddly to get just right, but in saying that, once I have them on, I've never felt any movement under my feet when climbing, even on awkward mixed ground. They do feel a bit heavy on the feet, but it's all relative, and they seem to me to be a pretty solidly built item.
