Lowering with Captain Hook?
Do you catch something securely, then change to a hook for the lower and release (with fiddling?)?
This is, of course, contextual. I don't go around rigging large branches off of roofs with a hook and a grcs... It's more for lowering small/medium stuff in certain circumstances where it just needs to be coaxed away from something like a fence.
I have done as you describe, and whatever else feels within my limits. When you take a full bag of tricks and apply each infrequently, it adds up to a substantial game on small and medium-sized trees in certain circumstances.
The fact of the matter is that when I put myself in a situation with a bit more pressure each time to do more alone with more tools, I gain capacity over time.
A lot of people criticize having a large brush pile at the bottom of the tree. It is not really an issue with a mini skid and saws lying in wait. With the southeast canopy reaching to modest heights, I can bail out half way through, manage brush, take lunch, and go up back to it. Each job is different. I still hire single workers, just less frequently as the gap between my capacity and my crane rental gets smaller. Also, I'm a 50/50 company, 50% removals, 50% other stuff, so I do a lot of solo reduction pruning. Look at my current workflow below - no need for employees, really...
Today I was "gardening" in a 30 ft. tall ironwood plus a 10" back yard laurel cherry removal for the arb trolley (so rough, I know...), tomorrow reduction/subordination pruning in a 18" diameter 40 ft. shumard oak next to house and a 14" elm thining/unclusterf*cking plus a crape myrtle removal, consulting and paperwork on friday, thanksgiving break, then finish a triple 24" spar storm damage hickory half on ground removal (mini is in shop with busted alternator bracket so this is delayed...), visual prospect crowne lyfte on sugarberry, 50 ft. climb to prune minor storm damage and inspect cabling on magnolia, 30" diameter hickory completely on ground to move and mill (uh-oh), brace/cable/prune two medium size cracked live oaks, large live oak half to ground storm damage removal, 80" diameter live oak brace/cable/prune, 5 live oak bridge construction project monitoring, prune 9" and 5" branches in live oak over roof.
I have nothing requiring assistance right now.
My last crane day was last month when I removed three laurel oaks - 40", 35", and 25 feet of a 65" trunk in a back yard. Finished at 3:30. Not fast, but safe, productive, and cleared my back log a bit...
I'll usually have a few big trees in Jan/feb/march, then the tax returns and looming hurricane season (june-nov) will start the big removal cycle again...
