I really like these cams. The alternating color system eliminates gear fiddling and allows me to quickly and confidently find the piece I need when I need it. The doubled slings saves a lot of weight and keeps my gear loops from being cluttered up with a bunch of extra slings. I like the longer stem for deeper placements, and I haven't had a problem with these cams walking any more than any other cam. I think these cams are a great value and are a great addition to your rack as well a good option for someone just starting to build a rack.
