In reply to smithaldo:
I assume you're referring to the Bladerunners?
I have them. Have only used them for water ice in mono-point configuration. They work well for that. Planning on using them this summer in horizontal dual front point configuration for alpine climbing. They are a little bit heavier than some of the more specialized crampons, but not by too much.
So far, no complaints. They could be a "quiver of one" for all your crampon needs.
