Use the two ropes and have your seconds simulclimb...saves a ton of time! I would say the question was wrapped up with the first response.
The continuing proctology is getting painful.
superficial advice: take two rope and do that. He will go to knife blade tower and take to skiny rope and...oops is death, the rope cut. it is what I dislike about some sport climber (not all)
what is the question? My concern is that managing 3 ropes on every pitch is going to get messy, be really heavy, back-up the route and potentially expose us to more objective hazards because it will likely add significant time to the climb.
So he talk about three rope and time to climb. He make a good research and bring the discussion to the level about a safety question of the rope rating and his manipulation. Even if I dislike the way hbbsj wrote his mail, he or she can have ask a question making me in trouble to explain it instead of saying that I am wrong and he is good, at least, he brought some thing to have a deep knowledge of climbing.
climbing with a deep knowledge of what we are doing is what we all want to climb high and safe.
