i think throwline to pull line transitional use is a Black Widow strategy. Sometimes to put some pull on a branch, we will just use a throw line, especially in a 2/1 pull with bag end whipped around an anchor a few times and crossed; while placed at high leverage position on target. Getting a 2/1 pull 30' from hinge on an 8"hinge/branch forces a healthy hinge fer me.
i think this gives more rotational input force; i even using it blocking out and catching underneath, and will make a small V with handsaw on rear top to act as simple keeper to pull piece over on healthier hinge, to catch in block underneath load with minimal shock. It takes very little to check it in place, especially on a flat zone, with textured bark and lots of pull trapping it there. i also can use the over the top line dangling in the face, as a positioning line (not counting as part of securing tieins) to muenter-descend and service next face more easily after muleing or locking muenter off and making sure i have 2 securing tieins, that this technique doesn't satisfy the 'counts' of.
On the rigging the fishing pole type strategy also places the direction of the rigging pull in line with the support spar, not a levraged angle to the side or down; but straight inline with the support spar axis, for least amount of leveraging of the support. Also, this causes a compression force into the parent spar to fortify the support inot the connection as system is loaded; if a pulley redirect brings force back to center of spar or so; rather than just angleing line off the end of support branch and reaching the parent spar later etc.
Or, something like that,
