I've had mine for quite a while now; I also have a Vertex, but I pretty much go with the Ecrin-Roc now.
I put a PMI helmet on at On Rope and it was by far the most comfortable helmet I've ever tried. Of course, trying it on in a store and climbing in it is two different things. It has a lot of webbing that makes it really comfortable, but one has to think that all that webbing would make it hot too.
Ecrin is hard to beat.
