scm007 -- I think we've all managed to overcomplicate your question. So, after a good nights sleep, this is what I've come up with:

I propose you end up with this --

Overview


it's simple... it's solid ... the loops are redundant ... its equalizing

The procedure is as follows:

1.) Grab both tails of your 50' feet of webbing, and work back to the center, making the webbing neat and flat as you go. This is the upper left point of the "V". (Edit: You could premark this point with a little rub-a-dub ink or tape to save time)

2.) Using your arms, measure for length (for most people this is 5'-6' per stroke). Tie a simple overhand knot here. This is the upper right point of the "V".

3.) Grab this overhand knot, and your original left side loop end, and work back to the center. Tie two overhand knots, each about 6 inches from the center point.

Now you basically have an equallete. No fuss, no muss.

The detail at the master point...lockers might be better.




The detail at the upper right of the "V"



I believe any wierdness loading the knot at the "crotch" is of little consequence in this application.

Cool Cheers

Edit to add: alternate detail for the upper right side of the "V". No "crotch" loading. I think I like this a little better.

Alternate upper right
