Here's one I climbed a few years ago. Mind you I am no way an "experienced Redwood climber", but I have climbed a few big ones. To set a line in this tree I used a very simple method my friend Jerry Beranek taught me (who actually took this photo). Its using a bigshot and changing the weight and line. We used monofilament fishing line and a 4 oz. Surf weight. With that setup I could hit 200' each time.
I would also stress that at that height you cannot tell if the branches are going out or down, so you simply trust them. We also employed the many branch approach paired with as much of a wrap around the tree to a base anchor.
Last I would also leave the possibility of dual ascent lines, dual anchors and in opposing directions. Hope this makes sense.
