The thing I hate about videos like this is that it is completely impossible to judge lean.
Especially kinda wonder on head lean vs. spar lean on this; and then where that puts balance of pulls to hinge.
.
Maintaining far part in hinge for anti-spin always good, to not shorten hinge across face because of this leverage, even if center punch.
.
On any truck etc. pulls,
i look for good ground, put weight in back of truck(make sure has gas..);
AND, (at least consider) a low redirect pulley;
so equal/opposite of truck pull is not upward pull on truck;
so not losing traction the farther out you run..
.
Low angle line straight to truck would not lift up on truck as went forward like high angle line does.
.
1000# pull from 40' up from hinge/pivot = 40k of force leverage on hinge forward.
If nothing else wedges easier!
Real trick is if that distance encompasses or otherwise controls the Center of Gravity(CoG).
Focus on move CoG, rest of tree goes with!
.
And of course a few pulleys to make truck a 3x1 pull,
go higher with line,
pull harder with truck, winch etc.
are all multipliers that can be stirred in.
.
Still Billy Ray is artist and showman in own rite!
And makes VERY relevant point that as making face in Backleaner, are allowing it to sit back into anti-target.
As RB says, as climbers with the magic of ROPE in our repertoire; and easily putting it into position, we can see something different!
