Similar to this? 

Not sure when in the video it shows it, but a useful idea with having your rigging end of the line on a pulley with a prussik to allow for extra tension. Only good if your speedline is anchored in another (higher) tree but a clever idea non the less 

Nice one, before he got the crane, more interesting vids then.

those slings dont look ideal tbh mick, bit chunky for side branches i would say, i use either rock climbing slings or thin cord kinda prussic diameter, then make a closed loop with a double fishermans knot then larksfoot that onto the karribiner,

i have a rack of ten of them mainly for side branches, you need a good few of them on spruce type trees as you can send down a whole load of branches at once, or at least be climbing around setting slings while you wait for the ground crew.

i think i put a picture up here of my set up.

the rock climbing slings can be quiet cheap and are super light and you can buy a few different lengths so you can select the best for the branch.

Slings are ideal fo ziplining branches but if you're chogging down a stem and zipping the sections away it's a good idea to cut a notch in the section and tighten a cinched sling into that, pretty much guarantees that the sling won't slip off.

They’ll do for my purposes.

Are you going to tie them on? Just curious as I've always used Lyon slings but cost adds up, think I've got 6 or 8 something like that.

I’ve put a big loop with a bowline at the end (poor photo, difficult to see I know)

I will girth hitch the branch (is that the right terminology?) the snap the Krab on the zipline.

I made up my zip kit with 10 of these from Skyland, and 10 webbing slings.

About a oner all in.

 

You should use steel crabs not ali.

I wouldn’t zip chunky cord if I could help it, that’s normally rigged conventionally then pulled with a tag line if needs be.

If I was speedlining and making a job out of it I would have a rigging plate off a pulley on a taught line.. below where it was anchored high in the tree I would have a second pulley with a second line attached to the rear of the rigging plate so the speed line can be pulled back to you and controlled speed in ascent to the DZ.

off the rigging plate, then have two three meter lengths of dead eye off the rigging plate  that can be used to balance or tie off whatever your cutting. 
straight out balls speedlining just slings and crabs but I’ve found the above handy easy and time saving in the right situations. 

Every time I 'straight out balls speedlining' I just melt my rope. what rope you using ?

Ah I see them now, see what you mean.

 

Not sure, usually think of girth hitch done with a loop but principle is the same, not tying knots each time.
