Interesting discussion over on the taco about the BD Ascenders slipping... Too many moving parts for me. www.supertopo.com/climbers-forum/1028930/nForce_BD_ascenders
And here too... mountainproject.com/v/climbing_gear_discussion/bd_nforce/106>>> I had 'em slip a bunch. Lame.
I just took mine up Moonlight Buttress. Jugged 400ft of fixed rope the second morning with no issues whatsoever. -Richard
