That is a hand saw cut for me when I have to be extended like that. Won't take a few seconds longer with a Sugoi. Go back to what i said early in this thread: I've decided that there is always another way - and I have yet to find a time when there is not.
I use a Silky Zubat quite often.
I don't see one handing a top handled chainsaw in the tree as the '11 commandment'.
There are no rules or government declarations that will ever make tree climbing and removal 100% safe.
Do you ever one hand a circular saw doing carpentry work? I do on occasion.
