With a pole snake a loose sling up that carries rope ladder or etriers (spelling?), climb to sling that was raised with pole, lock off. Then, pull 'stairs' up, same trick raising the once bottom of ladder with pole, release first sling (so bottom is always loose for pulling up). Alternatively, without choker, you coud use top loop as choke; or a line with lineman's loop, that would give remote release if it hung up, and something to lightly steady yourself. With these alternatives, you would always have the same end as top, rather than flip/flopping it. The line should be threaded through itself, ie. not using a 'biner that would be being flat metal stressed against a round surface with direct pull.
Have a lanyard that is in a round turn rather than just once around configuration, hold the choking ring open; if you were to slip; it would catch you positively, even if unconcious.
Descend with climbing line through appropriately sized "Friction Saver" that will fall off when line is removed. If some are close to each other, you could save time and energy by descending from taller to smaller.
In a "Ben Meadows catalougue, many, many moons ago; i saw a pricey swiss(?) bicycle for climbing clean spars to collect seed samples, supposedly without marring the tree.
i think that coconuts are pretty hard and heavy for standing on ladder and knocking out with pole; at least that is what i understood the imagery to be................
