In reply to Martin Miszkowski: Yeah, I got a couple of them to complement DMM Wallnuts and HB Offsets and I really like them. First I did not think their shape were very useful but now i place them everytime. One thing to note though - check the sizes on the Cassin website, especially if you are buying them on the web. They are NOT the same sizes as wallnuts/rocks, a #1 Halfmoon being equal to a #5 Wallnut or something like that.
