The Firefly has the largest gate clearance, making it the least likely to trap your fingers—a good pick for folks with meaty digits. It’s also the easiest draw to grab; I could just squeeze four fingers around its spine. A good pick for those hoping to shed weight but not wanting to skimp on function. The non-anodized Firefly biner, however, would not open under bodyweight, yet the anodized version would.
