well, you will NEVER have 100 ropes in a tree
climbing with a single tie in is STUPID
T.I.T.S is a SUPER important rule, even more so as an inexperienced climber that will be more prone to gaffing out or not knowing where their bar tip is in relation to ropes
no amount of extra ropes in a tree adds any more danger if you engage even half your brain, ropes can tangle, but they shouldn't, with a half decent climber and ground crew, they won't be tangling or snagging, same goes for a rope going into a chipper, EVERY piece of brush should be inspected before going anywhere near a running chipper or a machine of any sort
I have fallen just rappelling out of a hackberry once, ***** not fun, my zigzag locked up somehow and wouldn't grab the rope, kicked off a limb at about 40ft, came down a little faster than normal and when I tried to slow down at about 20ft I had nothing besides the friction of my rope over a limb, so I won't ever make fun of someone being tied in twice even if they aren't cutting, equipment can and will fail, ropes can get cut, especially under tension, even without you touching a saw to them, the tree can fail, etc
I was working for a half price harry a few years ago, im up in the bucket rigging down a red maple, alternating ends of my rope, I send a branch down, tie the other end of the rope to the bucket as I am re-positioning the block, I felt the bucket shake a little and look down to see the limb being fed into the chipper, dumbass feeding the chipper assumed the other ground guy had untied the rope, thankfully one of the 2 other guys saw it and stopped the chipper, I came down out of the tree and yelled at the kid, showed him the "rope in chipper" video and basically told him if I ever saw it again id probably end up with some jail time for beating him to a pulp, he never did it again!
working on my own, or with a decent ground crew, never once have I been even remotely close to being pulled out of a tree, but that one moron almost ended it all right then and there
so, don't get rid of the thing holding you into the tree, get rid of the thing pulling you out of it! 2 tie ins minimum, often I will go up with 2 lanyards and a climb line depending on the tree and how my nerves are that day (I don't climb as much as I used to, maybe once or twice a month now so I get a little shaky sometimes)
