Yesterday when i was climbing down (luckily in the light), i noticed that the one strap lock on my LWHC had opened up and just barely had a hold of the strap that goes around the tree. I tied to gingerly get it to bite in the tree so i could close the latch but of course it fell. My Safety line was attached so i only had about a 20 minute inconvenience to get it reset on the tree & get climbing again. I think my boot caught the latch and opened it up. Has anyone experienced anything similar? Either way i think i'm hanging the HC up for a while and may be in the market for a new climbing method.
