I was surprised how much the biner mattered to the smooth operation of an ATC in guide mode. Switching from a lightweight locker (e.g., nitron) to a more traditional locker with a round profile (e.g., petzl attache original, BD pear) made it substantially easier to pull in slack, even with a fat 10.2mm rope. |
