Aerial face-cuts get overused a lot when roping. Face cuts give directional control. If you don't need directional control, its not needed, frequently.
.
i think facecut can be used for softer dampened hand-off to rig.
In some scenarios even think of it like a 2nd hitchpoint along with the rope much further out on load in a basket between both.
Use hinge like was a rope that helped position real rope's hitchpoint directly under the rig point;
then cut hinge free; like was a temporary butt tie.
>>actually evolved to this strategy, after using a temporary butt tie w/quick release or simply cut thru after using to position to main rig w/less impact.
.
Also; when rigging to side; rope will normally slacken as load moves toward it;
use some hinge force to direct away from hitch point; tightening rope more, not less, then start downward tilt on tighter line;
then let that tighter line pull load back around proper direction as also allowing with saw.
.
Some directional in each yes, but also slower movement into position before tear-off hands off to rope.
****************************.
Would commonly kerf-face lean side of a top; sometimes dbl.kerf face; then perhaps nip from sides some too;
to try to setup for fastest back-cut into a slamming kerf face /dutchman force used to launch pine top over fence etc.
.
Look at full face dutchman of full face kerf on lean force side; this offers NO relief path on close
>>a more step dutchman would only close lean side; and offer open path of relief/path of least resistance calling coyly out to raging forward forces of felling offering the offside;felling into the balance between the 2 calling forces
.
i think in comics imagery of a binary(either this or that; once force loaded/empowered) computer logic of programming commands given for a program to run thru:
Close of force across on fiber column's minimals axis/grain is a mechanical-logics flex command; unless not enough force can seize
Close of force inline on fiber column's maximum axis/grain is a mechanical-logics stop command; unless too much force can shear if heavy/ launch if light
If whole tree is on top; it is dead stop if not split decision of Barber chair as the internal forces are still raging forward; over ruling the constitution of the spar column.
If only small top is on top of same type early full face dutch close can seize or launch top, try to set up and slam close faster for more launch.
>>(felling or topping w/full face dutch into lean that offers lean side no open path of relief/full face dutch)
i always try to disect the mechanics and view in climbing/felling/bucking and then prove reverse strategies to view all aspects and prove same to theory.
