DMM Dragon Cams
The Dragons hold their own against both the Wild Country Helium Friends and the Black Diamond C4s. The head design is almost a carbon copy of the Black Diamond C4, so if you like or are used to BD’s cams, you will likely enjoy the Dragons.
As mentioned earlier, almost all the meaningful innovation in the Dragons is located in the stem rather than the head. That is not necessarily a bad thing, however, and if you are a Wild Country Friends or Metolius devotee, the Dragons will fill in the gaps in your sizes nicely and make great supplementary cams.
The versatility that the sling design provides makes them an attractive option for anyone who climbs aid as well as free, but doesn’t want to have two dedicated racks and is looking for gear to do double duty. While I really enjoyed the extendable sling, I can see it requiring a little getting used to for some people. If you worry you are one of these people, then buy or borrow a single cam and feel it out, otherwise I would recommend them without hesitating.
