RE: When do you use a harness?
Maybe, Bbear....but from what "they" say....that's when you're most prone to fall. I don't get why it's OK in some's eyes to only hook-up when they get to the top.....but like I said....i did it in a climber and have for 3 seasons.
Funny thing is.....whenI had lock-ons....I used the summit system and hooked up before I left the gorund.
