Cow hitch is my first choice but I still use the timber hitch too.

Stable braid is my favorite sling material but I also have a Tenex sling. I use both. Get more than you think you will need. You need more than x2 the diameter of the tree to tie the cow hitch.
 
timber hitch

:agree2:

Why do you think it is called a timber hitch?

Unlike the cow hitch, which can be pulled out, the timber hitch is self tightening. The more you load it, the more it holds. Most folks don't trust it because it is so simple, it looks unreliable. Tied wrong, it won't hold.

If you really, really don't want your rigging to slip, use a stilson hitch. Self tightening, it combines elements of both the cow & timber hitch. It also uses a lot more rope to tie.

The cow hitch is really nothing but a clove hitch with one of the 1/2 hitches done backwards. That makes it untie easier, but it also makes it a less secure hitch. Neither is rated for attaching to a load that can roll. Tied with a circular loop/sling, the cow hitch can't be beat.

When I am rigging a branch for lowering, I like to put a marl in front of the timber hitch just to make sure it can't shake out. Stronger, too.

I may have started a feud

I decided to do a little bit of checking up on my terminology. There seems to be a bit of confusion as to what a "cow hitch" is. I'll bet you guys that have said you use the cow hitch are referring to this knot:

That's not really a cow hitch, unless you happen to be talking to other tree specialists.


Here is the true cow hitch:

I run a 12' stable braid dead eye for 1 of my 5/8 blocks, timber hitch for larger diameters and cow hitch for smaller. The other block gets a whoopie sling for when I'm feeling that whoopie vibe. I should pick up a 3/4" block one of these days and some Amsteel. I like the stable braid though for taking up shock load and ease of tieing.
 
I use a amsteel loopie sling for hanging blocks and an amsteel whoopie for porta wraps.

i think i might just stick with the eye sling for now. im pretty set on having a 15 foot 5/8's made for me.
 
Just to be a PITA...

I call the first one a cow hitch and the second a girth hitch or a 'lark's foot'...howzat for messing up names!!

Maybe someone should have scientific nomenclature for knots, then we'll always be on the same page...or not:help:

I have always used whoopies in Tenex for hanging pulleys. Never having used a knot I cannot help there but as I have always used a timber hitch for attaching the porta wrap without a single failure ever, if I had to tie a knot that is the way I would go. I use an eye sling in 5/8 Tenex as my porta wrap anchor and the only "failure" I have ever had is when some bonehead (me) tied the timber hitch too loose and it ran up the trunk with about 400kg (1000lb) of block attached to it. Even then the knot stayed firm and the sling grabbed a metre or so up the tree.

Sometimes we make things more complex than they need to be.
