light n snappy
I recently got these in a posiwire quickpack and they've quickly become a favorite rope-end biner.
They are slightly larger than the BD positron biners, with less weight to them AND a much snappier gate action, even compared to most wire gates. This means huge gate openings for your rope end and a nice secure feeling when taking whips.
Anodization on these things peels away pretty fast, but they're not there to look pretty. Construction is great, they're thick for good durability, and they feel wonderful in hand. Always a nice smooth clip with these babies.
