I made one just like that except it's adjustable. 2 locking revolvers with a locking shackle on the end to catch the retrieval ball.
If it's too floppy-flimsy, it might get stuck more.

if you really want to climb off a pulley why not just set one in the tree whith an extra climbing line as if you were going to use it to rig limbs, then you can easily retrieve it too

How about one ring one pulley. I've messed with this bit. I'm concerned that the pulley will load unevenly when the ring snugs up to it. Thoughts on the uneven load on the pulley not sure it's an issue.

Nope, not an issue. I have three adjustable friction savers, carabiner on one end, pulley, biner the other. no problem whatsoever.
There is a lot of stuff to potentially hang up, however.

You could also use a small ring (tied with a Prussik w/ some slack) off of one end of the FS with the rope passing through it, that way a retreiv-a-ball would still work. Crude drawing attached.

Yes, great idea!!
I reckon buying two revolvers can make sense now...and free up a micropulley.
how's this for a thread bump! 3months later.....
I bought two non locker revolvers back before the locking model came out....now I have a reason to buy more gear.
I like adjustable friction savers (Nick has made three for me)...and pulleys/biners for the ends. allows for quicker resets...especially if the rope in use isn't spliced, requiring retying the termination knot.
Thanks, Tom.....I guess....

Setting a static retrievable f/c is great for tree entry. We do it often....but, for working off, not as much so. Requires being ever mindful of the second line. Touch it with a saw and ...
...game over...
groundies can't come anywhere near the line either, or...
uhoh.....

I have workd with a F/C for rigging and climbing in the past. I have been using a pulley it for a while now and have found no problems with the ring snuging up. Although it was a worry to me as well. So for just my peace of mind I have been setting the F/C in the tree (remotly) on a girth hitch. I made it retrievable by attaching a old throw cord onto it. This way I can move the cord anywhere out of the way and work. This takes the groundies away from it and also if I do mistakenly hit the cord with my saw it will be no big loss.

Ron did a test to find out how much friction is displaced using Revolvers. I don't have the numbers in my head but it was a surprisingly little difference over just running a rope over an aluminum biner. I think that using a large diameter stainless steel biner would have even less friction.
The Revolver wasn't meant to reduce the friction in the way that arbos use the biner. Under full loads with larger diameter ropes the rope rubs and reduces the friction gain.
I don't have a unit of measurement for friction reduction but lets use FR for discussion sake. The FR to $$$ ratio is high using Revolvers compared to a simple ring/pulley FC. Is the gain from spending more money to reduce friction worth it? I think that at the end of the day the calories saved by having a high efficiency FC could be saved by getting rid of a bit of weight somewhere else in a climber's system.

Thanks I'll be using one on my next climb
