Here's an equalette with a 4 strand powerpoint, and just two knots. Additionally, the knots are standard, tested double fishermans. It eats up a bit of the cordelette, but if one really wanted some more, just buy longer cordelette (the two pictured are each 21 feet long).

Left: The setup before the knots are added (ignore the un-joined ends, I was lazy).
Right: Setup with double fisherman's knots. Clip the bottom four strands with a biner and voila.



The DB fisherman's knots do not join together when the four strands are loaded, because pulling on the four strands pulls them together and apart at the same time.

Now, I just made this up about twenty minutes ago, so it hasn't been tested in any true way, but it passes a good foot-and-hands tug test. I originally sat down to create a trenchelette, but I got side-tracked and made this Laugh. The only way it is better, that I see, than the trenchelette is that it avoids a made-up, un-tested (although probably secure) knot, and is composed of half as many knots. (Edit: I just remembered that it was, in-fact, tested by the pull-tester. However, it hasn't been tested by time Sly)

What do you think?

Edit 2: Oops, I have no clue what would happen if a strand of the powerpoint was cut. Perhaps death. Someone else that thinks better in 3D could answer this. (No, I'm not testing it experimentally Sly)
