Interesting self Rescue Event.
After spending the overnight Saturday camping up in a treeboat in my backyard tree it was time to come down to the real world again. I collected some of my gear put on my New Tribe harness over my "sleeping harness" and lowered some of the gear in the hauling line down to the ground first. I decided to install my Grigri right below the split tail line on the single line that I have used to climb into the tree the night before. No big deal so far. I managed to go down slowly controlling both the Grigri and the Split tail Blake's hitch above it.

When I was almost to the ground I let the split tail run up the SRT line and lock up firmly on the down rope. I was stuck 5 feet from the ground without any possible way to release the tight grip of the Blakes hitch on the single line rope. I would like to hear your suggestions to see how I finally managed to lower myself to the ground without cutting anything or ruining any gear. Possible options move back up the line, release the split tail from the carabiner (Not possible, since it was opposite to the Grigri), no knife to cut the split tail line. You can consider the gear hauling line as part of the rescue options. Good luck rescuing me!

I can think of 2 quick ways (I'm sure there are more).

1st: Create a loop in the downrope hanging below your Grigri. Use the single footlock technique to reach up and grab the Blake's hitch. **If the bridge of your split tail is pretty long, that probably wouldn't have worked - you wouldn't be able to reach it.

2nd: Do the same thing on the line that you used to haul your gear (assuming it was life safety-rated rope and had a good anchor, yada yada). You'd have to hang on to the haul rope with one hand and reach for the Blake's with the other - seems like you'd be swinging around a bit.
If you had an accessory cord, you could tie a prusik on the haul rope and clip it to your saddle. Then you could capture the progress that you made as you inch worm up the haul rope to reach your Blake's. (So basically doing SRT on the haul rope using a prusik - but it'd be safe because you're still tied in to the main SRT rope.)

Oh wait, I guess you could also do a 3rd option: Do do a footloop on the haul rope enough to unweight the biner that is connected to the split tail. Unclip that biner to release the split tail. Then you'd be able to go down the main rope on just your Grigri. Of course, then you have to go back up to get the split tail...

So, did you REALLY do this, or is this a mental exercise? If you REALLY let the split tail run up, why? (Not as a critique, just wondering.)

Foot lock up the tail hanging from the gri gri, then release the blakes?

Nick and I got jammed up together...

Yeah, I was wondering if that would happen.
