I just wish they were made here!
I just started aid climbing and I love these things. I have a set of old tech friends as well as a set of C4's. I'm covered for most any crack size but I will be buying another set of these for the really little cracks. The area I climb most is small cracks and a second set of these will round out my rack just right. I've actually hung off the grey one.... these are bomber. I am going to try the small Metolius before my next purchase though.. not because I don't like the C3's, I just have heard that Metolius builds their stuff here in the US and that has been gaining some importance with me and the way I feel about Global Corporations and how bad they have F'd up our economy and enviornment. But I do have a feeling that these are going to be hard to beat..
