top to bottom
Top positron biner feels nice in the hand, super smooth on the clips, and is slightly smaller than the hotwire bottom. Bottom hotwire biner is incredibly light for its size due to the hotforging, is slightly larger giving that massive gate opening, and feels great in your hand! . . Did I mention smooth and effortless rope clipping?
Dogbones are 14mm wide now which makes them much less prone to twisting than the older 10mm ones, and even easier to clip. Only thing I don't like about the BD dogbones are the rubber inserts on the bottom loop as they are sensitive to tearing out if you're swapping bottom biners. Good thing you'll never need too. .
