Sure is.
For smaller trees up to 1 foot diameter, I use the lever a lot for falling.
Not the one Fiona shows, but the big boy version.
The small one is just handy when you've misjudged lean on a top, which I guess Sean never does.
If I'm ever in question about the top, I use a wedge. A large wedge will pound a small wedge for a tipping a top, if swung like hammer. I can push a small top pretty hard. I can wedge over a top with a hatchet if its bigger. If the top is resisting, gutting the hinge from the face-cut is reasonable. Once you have the top on the run a bit, you can more confidently 'tickle the face'.
Mick, I generally will block down logs past the bar length, and try to avoid pulling up bigger powerheads with longer bars, along with repetitiously pulling up pull-ropes that ground crew have to detach from under a log before sending back up. Since I have to tie the pull rope on the top of the spar, before I can move down to my new cutting position, I have to sit and wait.
My preference is to cut with the smaller saw I have, as long as its practical and fuelled/ sharp (all I'm doing is pulling the trigger, dinosaur-juice does all the work), avoid pull ropes when I can, and let my groundman do something else, staying out of the dropzone all-together.
There almost always work to do somewhere else.
Alternately, the groundman can be ready with the loader, having only the loader and log to think about, if I do not want logs in the dropzone. I cut, he drags out of the way, I cut, he drags. Keeps it simpler, IME.
If its just firewood logs, and the bounce doesn't risk anything, I'd rather drop a log on a log on a log, then come down and quickly grab them with the loader, rather than wait on the groundman to slowly do it. Keep from embedding dirt or gravel in many pieces, which are harder to check, than have one or two bottom logs that needs the cut-path cleaned of some gravel or dirt, maybe with one chain sacrificed to do the dirty cutting.
I'm very injury-averse. If I need a pull-rope, I use one. I don't have 'oh shit moments' regularly or anything. If I really scare anything, its a fence or vegetation of some sort, not people, most especially myself. I don't cut my hinges off. I've assessed the lean of a tree a time or two, and worked with or against it.
While I could use a 460 or 461 for ground work, I stick to a sharp 261 a lot. I can take a bit longer to cut, if it's quicker, lighter and less straining on my joints to position. Clearly, if I need a 661 I use it. I've felled with an 880 and 60" bar.
It's not for lack of skill that I'm aiming for smaller and lighter, with less repetitive movement. All we do is eat elephants, one bite at a time. We will be eating elephants for the rest of our careers. I'm looking at it as an ultra-marathon.
Mick, I'm not sure what you're 'fighting weight' is. I used to work with a guy that was 6'3", about 240. He didn't think twice about one-handing the 200t with 16" bar. It hurt my wrist and shoulders. 12" is better. A 193t with metal dogs and a narrow kerf bar does a nice job, like that little Echo zipper you got.
The Magic Cut is worth at least as much as you've paid for it.
