Where applicable please could you list your chosen application for the knot in question, size cord you prefer, length of cord(or loop in some cases), pros and cons, etc etc...anything you can think of really. Thanks

Nice, but can be a sod to undo

[Alinicoll]

This is the knot i use for tying in mid rope to create mechanical advantage. I find it easier to do than a carters hitch.

[geoff]

Mid rope on light rigging if I only have one rope & want a tag line as well as lowering rope.

[Paul Smith]

Used as my TIP on my SRT line.

[arbogrunt]

midline knot for cross-rope for tying off speedline (rarely), as rigging attachment on big-girth trees or type c aerial rescue using end of climbers rope (but only if its long enough), for pulling with tow-hitch or as a winch attachment (with a piece of wood through the knot so it doesn't over tighten). The only problem I have with it is if I haven't used it for a few months I have a brain fart and forget how to tie it!

[treequip]

Alpine tied with a big loop makes a great handle on a rope for pulling a tree over. Three tied close to each other allows a big pull without the man at the front getting lifted off the ground.

[bob]

the only knot that can be tied mid line for pulling tight both ways and allow an offset pull

If heavily loaded can be awkward to undo

relatively easy to check tied correctly

very useful knot

probably mainly used in tree surgery when applying mechanical advantages or offsets

Tied mid line

[Big J]

Use it mainly for tying down loads on trailers or as a loop for pulling over trees. Absolute cow to undo if heavily loaded though, and when heavy loading is expected, I use a midline bowline.

[Old Mill Tree Care]

I use it for mechanical advantage when pulling a tree.
