Wow, good point!
i like guying them against lean. Perhaps tightening guy line as weight comes off and top stands up, slackening guy, allowing impacting of desatabilized head as you werk. But, that only happens in bigger ones.
In straight pines, i like 3/1 pull one way, then gently tighten back to straight with the truck the other way. i look at it like welding 2 braces, at that angle of line, to the leveraged point of the spar.
Then sometimes i will tie in to that area, sometimes even below, then feed lifeline up through choked sling/'biners, like a mountain climber picture, imagining fail at several points, and how i would be caught, with minimal fall. i use my rigging slings for this on the way up, topping off with my saved lifeline re-direct sling, that will be downgraded to rigging at some point. The slings after set make good hand holds, mini footholds, click right to belt as werking way back down, and for rigging some. When ever i use any rigging stuff for person-all atatchment,, it is always for safety, over and above the recomended 1,2 tie ins required. So i am tied in with lifeline, have lanyard dead manned around spar, and might use an in place sling, especially if it is the most comfortable attatchment and closeness.
P.S. i only cut threw the hinge after force and face are committed, can be tricky and all of the sudden, therefore the precutting and saw choice to facilitate immediate detatchment, and the making positively, mechanically sure it is moving away from me, also pushing base with hand.
Things fall from their center of balance, so if you pull below it, it can leave that center of balance behind, to come straight down on ya, you have to take leverage and/or power over the center of balance, and pull it forward.
