Was looking at options for self descending, without paying for the $250 Petzl D200L0 type of ones. So can something cheaper like this: http://www.backcountry.com/mammut-smart-alpine-belay-deviece-8.9mm-10.5mm?CMP_SKU=MAM0491&MER=0406&skid=MAM0491-BLA-ONESIZ&CMP_ID=PLA_GOc001&mv_pc=r101&utm_source=Google&utm_medium=PLA&mr:trackingCode=9C42F9AC-0F6C-E011-9898-0019B9C043EB&mr:referralID=NA&mr:device=c&mr:adType=plaonline&mr:ad=56125866277&mr:keyword=&mr:match=&mr:filter=100043054197&mkwid=sR3IY1GqP_dc|pcrid|56125866277
........ be used self descending, or is it only for a person belaying someone from down on the ground? Thats what I wasnt sure of, because it says it can catch falls, so if it has braking capability, could it be used for self descending?
If not, what about the Petzl Grigri 2, which is about 90 bucks?
Thanks
