I have been spending alot of time doing municipal and association work, rather boring mostly 12" to 25" Ash. Today I did a private job, 5 large Burr Oaks to prune the deadwood. Best part everything stayed. 3 man crew 2 climbers and one ground man. No obsticles under the trees either. Had three done by 11:30. Ropes in the next two than we ate.
Good Fun

I ascended via SRT with a floating anchor and pruned half the tree this way. To do the rest I needed to be tied in higher. So I took my prusik rope guide installed it on a stem and tied the tail of it back to the floating anchor. This makes for easy retrival. When I use SRT I usually have to eventually tie in higher and do this often,works well. I hate using string to makes sure the RG gets down.

Tod,
That must be a fun day. Any of the white oaks are the best climbers!
When I anchor my SRT I use a Gri gri like you. Take the rope and tie a slipped half hitch above the GG. Then make another loop on the top of the loop from the slipped half hitch. leave it about 12" long, from the slipped half hitch. With this setup a groundie can untie the lock-off easily in case of a rescue. I've used this tieoff for most of my career. Tieing down brush and log loads etc. Never had it loosen up or drop the locking loop.
It looks like the figure eight on a bight is clipped into the anchor biner. If you needed to be lowered wouldn't the biner need to be opened? If the biner is loaded that might be difficult to impossible. Besides, there is a too-likely chance of the GG slipping off and the climber taking a ground fall. Ouch...

If I took the time to set something like that up, my boss would kill me after he got the extension ladder off the truck. He makes fun of me for using throwlines and friction savers.....

Zac,
After you got skilled at setting up SRT you'd be ready to go, in the top of the tree, in a shorter time than ladder climbing. Maybe on a job here or there the ladder climbers will win out. But after taking in twenty jobs I'll bet dollars to donuts that throwlines and SRT will win the day. Remember, the ladder still has to be dragged back to the truck and lashed down too. How long and how much energy does it take to flake throwline?

Tod,
What about clipping a second biner for the figure eight bight into the same place as the one you use for the GG?

Tod,
I guess my biggest problem is that I'm trying to see what is going on with the system in 2D pictures, if I was on site for something similar I would probably understand most of it provided I had some time to look at it. Looking at the pictures and the fact that others know what is going on, I can see I am still quite new to advanced techniques.

dont think i like the rigging on that photo of the grigri anchor, with the blue rope coming through a gg!
As I understand it you've got to undo the anchor carabiner to undo the fig-8...
Thats the gear we used for setting releasable anchors in the eucalyptus trees...but made sure there was much more slack, because the grigri will slip a little, and then a seperate clip for releasing the setup. sometimes just would tie a big knot on the bight around the anchor tree....
Am i misunderstanding the setup? If not it would definitely benefit from the correction...actually, i think im just saying the same thing as tom just with more words.

Tom;
I'm not sure what you mean. '...above the GG' sounds like the slipped half hitch is made on the climbers side of the GG. And then another slipped half hitch is made---where??? Is this just two slipped half hitches in a row on the belay side of the GG?
