Yesterday, I had a terrible alder and a maple with a defect in the base. I threw 4 times to get a tight TIP-window in a maple with the defect, installed my rope with a base-tie. Bounce tested it. Gingerly climbed up the alder, not tying in locally, in case it broke, but a lanyard in a decent stem behind me for popping the top. Swing over, take care of the maple. Both trees down quick and easy with overhead support the whole time, after testing the high TIP. I was solo. Because I was supported overhead the whole time, I could sit in my saddle, swing around to wherever I needed, and throw all the branches into the chipping pile, oriented right for chipping, and could push chunks into the gravel to clear the rock-garden, power outlet, and asphalt.
As I said, throwline skills pay the bills, IMO.
IMO, you should have 3 throw weights and two throw lines minimum.
I'd encourage you to develop throwing/ APTA'ing/ Bigshot-ing skills, and bag manipulation.
Last summer I climbed a dead tree to install a pull line for ground felling. That the last one I can remember climbing for setting a pull line. Its the only one I can remember, as it had been so long before that.
Setting 90-degree retainer lines is a big help to stay on the ground, and fell trees, rather than piecing them out.
