To me, wedges are cheaper, lighter,more compact, but less usable range; and sawyer doing forcing as well as running saw.
Tree truck on site, loaded with ropes, generally go with rope, wedge in kerf as backup +added pressure if needed especially in soft or backlean.
.
Wedge has a complication that rope doesn't tho.
>>As bring hinge back further to easier fall/moving CoG forward
>>also works to reduce wedge leverage
So paint into corner of choices of wedge leverage vs. Natural fall leverage, mapping to same compressed part of hinge as pivot
In contrast, can bring hinge back further, and add rope at same leverage if not more angle/distance to hinge pivot.
.
i think direction of added pressure saw or rope; should be to target, not against sidelean.
Should force hinge stronger, and stop rope pull, like wedge Naturally stops pushing on movement/when she commits.
i like thinking of added forces as added weight like tree is heavier, so gets fatter hinge in response, then remove fake weight of rope/wedge force when 'births' /is live with movement.
>>then use stronger hinge to steer available thru whole ride, not just start!.
NOT to TEMPORARILY offset sideLean for sideLean to IMPACT back when tree moves(and offsetting sidelean force of wedge or rope stops), so rope/wedge against sidelean uses part of added force to 'baby' hinge weaker, not stronger in my mind 2 compounding ways:
>>taking force away from forward pull that could force stronger hinge for whole ride with better buillt in ballast
>>taking some sideLean away, that rebounds back in HARD when wedge/rope forces stop that were temporarily ballast against sideLean..
.
Climber's more attuned to using rope in tree for trix; extends that mental toolset to ground it seems.
>>conversely in tree have used semi trailer tire changing spoon as lever to slip thin spoon into backcut kerf for for rear lift with tempered steel bar, often as being pulled also with rope.
.
i do prefer ropes in a more over the top, or around the side in tree etc. bends on target pull,
>>as more of a cradling, rotating force input since we are trying to get rotational movement on hinge as output, rather than just Running Bowline around target type strategy of more of a just linear 'sharper angle' pull input not braced cradle roll effect try to sponsor.
.
Especially in a top that can give ANY flex / displacement:
>>becomes more of a braced, rather than a sharp flex >> which can lead to placing more confidently higher up and harder pull input
>>can also favorably effect Center of Gravity more forward with more confidence
>>spring loads pressure to tree elasticity as well as rope to force stronger hinge many times(timing of hinge movement in here some how tho).
.
i break leans into 2 parts: head lean and stick lever of trunk head sits on.
>>then how those line up across thinnest part of hinge as path of least resistance
>>assuming forward lean, or first job is to roll it forward and make it so.
From there can have forward forces across thin part of hinge and side forces across long part of hinge.
>>Tapered Hinge as side ballast against side forces to neutralize, 'simply' allow remaining forward forces to take her home to target.
Those are the 2 dimensions of pull across 2 dim hinge; 3rd dimension is downward compression from inline forces down trunk.
>>but last 3rd dim are neutral/balanced UNLEVERAGED forces bank of load weight, until that weight pulled off balance into fall as part of the LEVERAGED lean as she falls.
