Hasn't voted | Ed Leeper originally designed them for use in "Hard" SS pin scars. Another factor is the manner/technique that they are used. Of course, any "Newbie" will blow out delicate rock, regardless of density. That is a given. Besides, when I worked on Clean Aiding ZE in the mid 90's, it wasn't even close to being a "Trade Route". At that time, there weren't more than 20 or so ascents on the route and all the pin scars on P2 & P3 were "rock" solid. |
