Great compliment to the giga jul - Edelrid HMS Bulletproof Triple FG Carabiner

The Edelrid Bulletproof Triple-Lock is my go-to caribiner for belaying whether I'm using an ATC, Edelrid Giga Jul, or GriGri. The steel insert extends the life of the carabiner and the inner lock keeps it properly oriented on my harness at all times. When paired with the Giga Jul, I find there's more slippage in assisted mode than there is with the all-aluminim HMS Strike, but with proper friction and belay technique this is not a problem.
