Anybody ever use a whoopee sling instead of a cow or timber hitch to secure a rigging block? Seems like it would be alot faster and as long as you stayed under the stated working load it would seem safe also.

whoopie sling.
a whoopie sling is an adjustable sling , they come in half " , 5 eights , and 3 quarter " diameters. They work like a chinese finger trap. You see them used alot to secure a porta wrap to the base of a tree.

Keep in mind that the load on the rigging block and attachment sling will be a minimum of double the weight of the load, plus shock loads. It adds up quickly if you're hanging large loads.

I've been using loopie slings for a while now for my blocks after switching from spliced eyes. To be honest with you, I'm going back to the spliced eyes. With the loopies you have to take the rope out of the block each time you want to move the block. The spliced eye, it can stay right there. Plus also, I don't like the idea of just girth hitching the loopie to the tree. I am normally afraid that the thing is going to plummet to the ground when a big logs hits it. However it has yet to do that.

I use whoopies of different sizes for different applications as much as possible. They are faster for me to use due to the adjustibility and it seems that I usually get a tighter connection to the tree versus using a knot. Plus using the girth eye limits the possibility of mistying a knot. (don't laugh, it can happen) I agree it is very important to know the strength limits of the whoopie you are using, with a block that thing is taking some serious shock loads.
I have some made of 3/8" Tenex which replaces my webbing slings used for foot holds or redirects, 7/16" to 1/2" for light rigging in the tree, and 5/8" and up for heavier rigging.

I make and use whoopie slings and like them... but I find a simple eyespliced sling more versatile.

Those whoopie slings are excellent. I have used them a ton. I have also put alot of heavy loads on them without a problem. They speed the job up considerably. Now if I was rigging down some monster trunk wood then maybe a spliced tenex pieced would be better. I just get the whoopie slings in the tenex material and they work awesome. Use them every day.

Good links upped by clearance, so I'm bumping it.
Locally, we've been doing a lot of removals of trees that were shifting their root plates in a series of wind storms combined with 20 year high rains saturating our predominantly mineral soils.
I've personally watched a loosening root plate sway to one side, then settle back spewing out a geyser of water and small gravel and stones.
The trunk is as sound as heck, but I'll not be tipping a big top or rigging anything off that spar.
Fortunately, the customer is willing to have his garden and lawn pounded to hell and back, or it would be a crane job for sure.

Redline, check out the post Tom did about drop zone safety, the link talks about guys who free drop wood taking "great pride in putting all the wood in one spot". No need to destroy everything, I can put every block into a piece of lawn the size of a half sheet of plywood on a 100' fir. The groundsman moves every one and builds walls, easy on conifers.

whoopies rock! I use a long 3/4" tenex for the port a wrap and another 3/4" shorter whoopie for the big block matched w/ 5/8" bull rope. We also have several other smaller Loopie slings for smaller stuff. Fast and easier if you ask me.
