Can someone post a photo of the bottom of this rap? I'd like to know if I really need to have a 70m rope to get far enough down to begin a reasonable low-grade down-climb point. I've got a 50 and a 60m but have not yet invested in a 70. I would rather not join these two because of all the extra there would be to pull not to mention the high risk of jamming the knot in a crack. btw...nice photo!
