Thanks for posting that, RG! that device sounds like we're going to get it.
Now as for the ropes, I used to climb on 9 mm meaning 9 mm! I guess you can't get 9 mm double ropes, but you can get 9 mm single ropes now... what would speak against climbing with 2 identical 9 mm single ropes? I would prefer not to get and have to climb on two strands of spaghetti if I can.
