Don't speak too quick. I'm sure that your are at good will for static loading. It's relatively easy to stay conservative. But when the dynamique is involved, the actual force on the rigging skyrockets and it's hard to put a pertinent guess on what will going on.

One of the first things I learned about forces is that it all depends on how much it weighs and long it will fall and how fast the load comes to a stop will dictate how much force the rigging system will see. That's why letting it run is such a big deal around here. If you can slow a log to a stop over ten feet those forces will be drastically less and the same long coming to a stop in only a foot.

All true...but not always achieved even if it is the objective. The number of negative rigged pieces that for one reason of another failed to run smoothly might be close to the number which did, if counted from the beginning of time

And that right there, Burnham, is why I never could negative rig really big chunks of wood. I got paddleballed very harshly on a pine tree removal early on in my career. My hardhat ended up almost 50' away out in the driveway. That was the last time I negative rigged big logs while climbing. When I watch videos it looks so easy and so smooth, but my mind still won't let me do it if I'm strapped to the tree.

Hummm... wonder what's in the box?
I think the ups guys where doing some riggin.HA!
On a serious note,
Do you guys see a problem with the way I have the rope attached to the porty? in the pics it's a girth hitch just without the rope wrapped around its self. the ring on the bottom is wide enough to support the rope. To me I would think this way would be stronger because the rope bends aren't as tight as the standard girth hitch. Worst case scenario if the rope slipped down the ring it would just mean the rope would be touching it's self and look more as a standard girth hitch.

It's gonna slip down...count on it. And then it's a girth hitch, which may not be your best choice.

I would use a girth hitch, but I'm accustomed to seeing a much stouter sling than that...the smaller the diameter of the material girthed, the more possible damage to itself under shock loads. Clevis or 50kN steel carabiner are good options.
That webbing does look twisted.

In regards to the accender after playing with it more I believe one side is correctly twisted and the other side is twisted the wrong way.
I'm going to get a 3/4 inch sling but the 5/8 is going to be more than enough for now, considering I probably only take 300 lbs chunks at the moment. I do mostly pruning dead wood and the stuff that I am going to use the porty are on places that are going to have houses underneath and stuff so being that I'm overly cautious for one, I always take small pieces when there are targets for 2 and my work isn't production for 3 meaning I take my time and do the best possible job. I can for the trees. That means I usually take 3 or 4 pieces instead of one. And when I'm just pruning most pieces I am able to left by hand. That has been up untill this point in time. I'm starting to expand into uncharted territory to me. This next chapter is staring to be written and I'm excited to see where it goes! Thank you guys for being apart of it and steering me down the correct path and that's to everyone who has answer any of my questions.
I have an allepo pine that im dead wooding coming up monday, any tips?
