a synopsis, in my opinion.
People spend money to equip routes and would prefer if people reduce wear on them as much as possible. It doesn't take much effort to clean a route in most cases, so you might as well help out. In occasional situations it might be a pain in the ass, and it's not the end of the world if the rope runs through the shackles every now and then in these cases.
If you see beginners putting excessive wear on shackles, highlight it nicely but don't be an asshole, it's not worth it. |
