i'm not with the free climbing. But i think that with the left hand/arm outstrethced to extreme 9o'clock and the right hand outstretched to extreme 3o'clock to give balance and reach is fairly safe; and fairly hard to cut left hand that is 4' away from saw. The amount of extra balance gained givng safe footing and less fatigue; along with possibly less travel to thinner supports.
With an arm of fair strength; perpendicular from body and ropes; giving good clearance to potential kickback arc of a small, center balanced and supported saw; especially with inertia brake. i know i haven't had trouble controlling mine like that.
i guess in a sanitized, training session; not what you allow or reach for. But in exercised, professional use; perhaps a calculable tradeoff; of what is really, really maximum; without any kind of blinders on.
TITS- all ways, and always.
Very nice, professional film production; on any scale. The nameless, almost faceless, unthanked, no-dialouge stranger fighting the odds, with the background muzak; almost reticient of a genre of spaghetti western wit'squint Eastwood. Even so, when posting such things i guess we must remember; we are playing to a tough crowd; even if a world away; giving it all for free; can be a thankless undertaking.
To climb with or without saw; a personal preferance; on how much effort it is to lower a line, wait for saw,a nd if it will get hung up while being dragged up etc. i like better support anchor for my line on descending; and more friction, to break the necessary controlling friction in 2 parts of support and hitch; and not concentrate the heat in one spot; nor in hand.
i think that in some calculation to branch size, and leveraged force to chain speed/ sharpness ratio; clean cuts and seperations can be achieved. Next is cutting across with slight slant, so there is more leveraged distance of support on 'hinge' prior to seperation, by virtue of the 'hinge'/connecting fiber pattern being inline/vertical to the vertical force of gravity. Downward cuts, giving horizontal connecting fiber pattern near finish giving minimal leverage of distance from top to bottom(direction of gravity force) of fiber pattern. While cuts across; leaving tall, not wide connecting fiber pattern jsut prior to disconnecting, and in that tall vertical column much more leveraged support, that immediately turns to Zer0 on re-lease, for clean cuat and straighter drop. Whereas the downward cut with less leverage fading to Zer0, with not such a sudden change from lots of leverage to Zer0.
IMLHO 'woeful failings'(Phoenix) etc. seem a lil'strong here; smiting of contamination of compettyiveness.
