I bought a 25kg from them last year. Couldn't have been easier nor made me happier. When you consider the concept
of a plow (i.e. to help the farmer 'plow' THROUGH the dirt) the concept
of a Rocna and a few other 'modern' anchors is more like a PICK which climbers use to HOLD themselves in place. Somehow, for me the concepts transfer.
Anyway, I love mine and am very glad I have an anchor
wash down pump cuz it digs in deep and holds. Sometimes you can really feel it bite as you snub your line, not just hold but really stop you all at once. I'd go a size larger than recommended just for the 'feel good' concept. How detrimental is another 10# really in the scheme of things? How well do you like to sleep at night?
