Which Climber controlled Friction Setup?

I've got some small to medium rigging to do,( dead tree over a house), & I am
Having trouble deciding which to go with.

Safebloc

Limb weight will be <300lbs.

I like the concept of being able to control some rigging while aloft.

Thank You

I believe the AFB wjth 2 wraps is good to control 350 lbs?

Ive never used a safeblock but i know theyre probably stronger and have a user formula as well

Yes.

I believe 3 wraps is good for 1,000lbs.

I should reword:

What is the better choice when controlling 300lb loads while the ground man is busy controlling the tag lines?
 
There is two things I'd think about:

1. Long term needs
2. How much friction can you add in the system with a munter or wrap while a loft?

The safe block won't add as much friction as the AFB, but will be much more useful in the long term for heavier rigging needs. If you can set a munter or a couple of wraps behind the block on the tree itself, you can get as much friction as you want and be able to control it with a free hand.

Sometimes I'll leave a decent nub from a removed limb for this purpose...in fact for 350lbs all you need is a regular block backed up with wrapped friction behind the block.

With the AFB, your uses are limited to 1,000lbs, but you can add more wraps directly to the block

The AFB and the small porty are mid line attachable. Safeblock is not. As mentioned natural crotch offers a good deal of friction and only requires a rope you don't mind beating on. Sampson's Tree Master in 1/2'' will handle a ton of abuse and the load range your working with. Besides that 3-strand rope is cheap and Sampson is on sale.
 
In another thread, someone pointed out that a stainless figure 8 can also be used as a mini porta wrap. This would also be a handy option for light rigging without a lot of dynamic force.

Webbing sling can be girth hitched to the tree and the 8 can be clipped to sling with a steel biner

I have one set up just for that. I like to use it with the 60'Altec my partner borrows from time to time. I'll usually be on the ground during those times and I like having that 8 with me. Quick and portable to either side of the truck and it can handle some decent weight.
 
Recently for some fairly small stuff I just ran a half inch line through a small rigging ring twice. The bend is tight, and I assume the rope on rope friction isn't great for the line, but I handled a 300lb or so limb myself, and it didn't lock up like I thought it might be able to.
 
Interesting.

I used an actually mini POW wherever I was with a ring terminal rigging point.

It was so much easier than involving a rookie roper, and reduced time for groundie to be in the drop zone (coming under to install, uninstall line in POW, or taking off a half wrap when the ground started to bear weight.
 
I have not used the safebloc so I can't make any comparisons, but I can say for certain that the AFB is a great piece of kit. I keep mine on a loopie sling, and previous to that, it was on a 10' piece of double braid with an eye that was tight enough that it was a pain to take on and off of the device. That allowed me to open the AFB with no fear of it falling off of the rope.

It isn't without it's slight issues though. It either has very little friction, or quite a bit, then way too much friction. Fully wrapped up, it's a parking brake. One full wrap is what I use for 90% of my uses with it, but found I had to start taking larger pieces, or risk it not letting any rope through the system. It loves weight, but sometimes you will have to manually feed it rope if you are high enough up in the tree as the weight of the rope between the AFB and the ground makes a difference, although the same can be said for all in-tree friction.
