So can you set this in the canopy, the take redirects with your climbing line above the friction saver, and it will still retrieve easily?

I think "retrieve easily" is going to depend more on the tree species, number of redirects and rope angles. You're fighting the weight of the rope plus all of the friction created by the redirects.

Yes very! I've traversed 5 Firs before and it pulls out easier than a base anchor

the fact that it is named the "soft 8" makes me wonder if there's such thing as "hard 8" for this purpose. These are things i ponder on long hikes. My basic rescue figure8 (I think bought from REI maybe) is rated for 35kn and I can't image any branch larger diameter than i'm comfortable tying into would exert enough side load on it to blink an eye. Has anyone ever used rescue8 or figure8 devices as cinching canopy anchors. Is this a bad idea for any safety of practical reasons like shifting or retrieval issue?
What about cinching on a spar? would love to hear any ideas and techniques.

Pretty high chance of weird cross load- would not use

Directed at JeffGu's post, in the SRT Base Tied Tip forces thread I worked the math of 180 degrees rope direction change on single crotch/bollard vs breaking the rope arc into multiple segments - and they're equal friction. Where you get more friction from a multiple redirect rope pathway is when the rope doesn't stay in the same plane - because the sum of the redirect angles/"wraps" can end up greater than the single 180 degree wrap. Also if you stay rope-single-plane but zig-zag the path you're creating a rappel rack - again more friction.
Bored in the heat, computer break. @ the retrievability issue

Yeah, I was trying to create a cinching SRS lanyard that was kosher not "cross-loading" a carabiner spine. It was interesting but ultimately not what I wanted. I'm currently choking a carabiner to achieve quick one-handed install and de-install without fidgeting around or having extra stuff interfering with my lanyard use as is usually the case with the other possible "safe" ways to do a choked lanyard end.
Devil's in the details, too much subtlety in the ways to do it safely so it will likely never be an allowable practice in competition or mainstream tree worker use. So it goes, my use is integral to my climbing style and positioning technique for many years now.
Figure 8 use as a lanyard end has many possibilities, just not my cup of tea.
This is the furthest I took it, eventually turned one side of the F8 into horns. It was decent. it was remotely releasable but a little fidgety to set up that way. Not terrible though ;-)
This was my dream but no time or resources to move it forward

I would strongly recommend the texas tug. It uses a pulley and creates separation between the anchor portion and the retrieval portion. It's very low friction.

Or you could grab a sling and put something like a Petzl Rollclip Z or a DMM Revolver/Revolver RIg on one end and then a pulley/carabiner on the other end. Then install it like you would a friction saver and then knot block on the pulley end and climb on the other end. When it's time to retrieve, you'll have two pulleys to help you pull out redirects.
Looking at your drawing there have you tried/thought about one of the hexarope hands up?Yeah, I was trying to create a cinching SRS lanyard that was kosher not "cross-loading" a carabiner spine.

Check out the Cmi RollnAnchor for a cinched anchor that pulls multiple redirects. No need for the texas tug anymore. It also does a pretty stellar job in a pulley saver setup.
RollnAnchor Pulley
The RollnAnchor Pulley is machined from a solid block of aircraft grade aluminum and was designed in partnership with 3 Strand Design, owned and led by a field arborist. Its beefy tensile strength and flat surface make it ideal for use as a cinched canopy anchor. The pulley makes retrieving...

I think some videos of your new dealio are worthwhile.

Anybody seen the "American Clacker" yet? Buddy showed his to me and I loved it so much I made my own. I think he had Arbsession make him one. Its essentially two ring'n'ring friction savers that are bound by a floating ring. The savers are oriented opposite each other and each large ring of the savers will jam on the capture ring during retrieval. I use a DMM locking micro xsre spiked in the end of the line a retrieval ball. The xsre also allows for easy attachment of a throw weight so you can chuck the end of your line trough the canopy of the tree and then not have to go to the desired redirect union. This things uses two ropes so you need two independent climbing systems. It must be installed manually but retrieval is remote, utilizing each of the climbing lines. pic 4 is one I made with knots before I committed to splicing up a clean one. the red rope that is through both knot blocked alpines is just for retrieval. you can go through a ton of redirects and it'll pull out easily. You also don't need really long ropes.

In the works. I've come to accept I'm just not the guy to do it, as I can't focus on that and the work I'm doing, and I don't have time outside of work to do much.
