In reply to beardy mike:
Not claiming any special knowledge, but I have some and I found them much harder to place than current Rocks. Something about the shape just doesn't work well imo. Of course, others will disagree; I remember someone a couple of months back asking if anyone had any for sale, because he loves them so much. But, I think the taper is too extreme.
I have a set (from memory, 1-10 and a couple of doubles?) that I don't use and that I'd sell for £50 if you have a massive interest in obtaining some. Away in the Alps currently, though, and not back until end of the month. Not a plug, just a casual offer.
Hope you've had a good summer of climbing!
