@6:09 An important note is that the Edelrid rap line is rated for 2 UIAA falls for the twin rope test, meaning it must be folded in half and climbed in twin rope configuration, NOT rated for any single-strand falls. Also because it has non-elastic aramid fibers in the sheath, if you did take a proper lead fall onto that cord in twin mode I'd probably retire it after that since the elastic and hyperstatic materials would have a fight and something might break when it stretches that much.
My preference is a flat overhand bend (EDK). Petzl recommends doubling that knot...two EDK's back to back to eliminate the chance of the knot rolling under heavy load. With a properly dressed and stressed knot, rolling is not likely with low rappelling forces. 30cm / 1 foot tails.
Mark do you think the RIT-900 is still worthwhile buying for a 30-45m contingency rope for the bottom of The bag? Or VT-X is still a better option? RIT-900 seems very easy to rappel and haul with. Good compatibility with toothed devices.
I have with the micro traxion for hauling backpacks on a multipitch climb. It was fine for that. Tibloc seems sketchy even with the largest locking carabiner.
