Porti is on order someone lost mine on a job hhhhh.

In the mean time I am thinking if I run through xrr points I can control with a biner/munter or a biner/ eye-2-eye.

Am I missing something simple in the mean time without making a candy cane?
I thought about muntering a beast xrr but with lots of tail on a closed ring can be a pain.
Obviously pieces aren’t going to be overwhelmingly huge it’ll be moderate for now.

Thanks
 
I don't understand what you mean by " candy cane".

Can always take a wrap around the trunk.

Eye to eye used for added friction for heavy load sounds like a pain in the ass. Have you used one for added friction in lowering scenario before?

Munter and figure 8 are useful but limited if you really need to let it run quickly at the right moment.

I'm trying to alert @uselessinfo or @treespyder but not working. Hope it's an issue on my end, I really like his writing and knowledge.

I find that if I have 3 rings distributed around the tree there is really no need for a porty for anything 500 lbs or less. There have been times when the porty has added to much friction and I have needed to manually lower the weight from the canopy

I kinda thought enough xrr points spread around may just do the trick
 
I've got several ring slings and a porta wrap but I find myself using natural crotch on more and more removals. It makes running the rope up in the tree much easier as it adds the friction. If you need more you can wrap a stub or add a munter. 2-3 natural crotch redirects are normally more friction than I need for most of my work.
 
Overhead frictions reduce support loading but make it harder to pre-tighten thru same frictions. Loss of pre-tighten can impact back more force than reduced with frictions..
.
And for more load takes more frictions that are harder to pre-tighten thru.
.
i then fall back on 2 innocuous, inert sounding friends; that can be real game changing heroes.
.
Sorry, i thought i had more modern version on this 90's pic.gif (maybe left from ISA board) but am hurrying and cant find. Grey lines are supposed to be behind spar.
.
Last part of next pic evolved to leaving another extra line prussicked to Standing Part during cutting and lowering. When cutting and rope starts to take weight/tightens; ground control can pull extra line to turn load on hinge to position more under support. Also can bend line again when close to ground to give some steering.
.
The tighter the support line, the stiffer a lever it is to wrench rope even tighter. Sequential pre-tightening gives tighter and tighter/less rubbery lever to tighten rope more. As does waiting for it to have some laod weight on line to sweat/swig line during movement OR to force stronger hinge.

WARNING :both these seem like BS but are actually application of rawest forces. Both can impact with pulse of high amplitude force; if orchestrated correctly at correct time. Both of these are easily over looked science to apply in myriad of applications as potential game changers.
