For bomber anchors look no further - DMM Dragon Cam

I spend a lot of time climbing at Devils Lake in Wisconsin which is a trad area. I'm not a trad leader yet but you can hike to the top of most of the routes and build anchors to top rope off. Having a set of cams and nuts opens up a lot more routes than just slinging naturals. I haven't used another brand of cams so I can't compare them but I can say the extendable sling has come in handy to keep the carabiner from getting bent around an edge.
