Great concept but the range isn't all that spectacular. The small size has only a slightly larger range than the #2 Camalot, the medium is about a #3 and the large is about a #4. Another dilemma is that when you fully compress it, the cam lobs are pretty long meaning you need a pretty deep crack. The Super Cams are priced about the same as the Camalots, but they are slightly heavier as well. So between Super Cams and Camalots I'd stick to the C4's, even though these look so much cooler while compressing.
