braided dacron halyard -- twisting

[Brion Toss]

Hello,
First, make sure that your figure-8's are not in fact inducing twists: start with a twist-free rope, coil it, stretch it out, then sight along its length to see if it has twists in it.
If it doesn't, anchor one end of the rope to something solid, and pull on the other end (or some distance away from the first end), and sight along it; if the problem is in the rope, it will show up when you tension the rope.
The site you refer to was deeply mistaken to recommend clockwise coiling -- and counterclockwise would be just as bad -- but neither one is likely to produce dramatic problems, at least in the short term, so my money is on unbalanced rope. Let us know what you find out.
Fair leads,
Brion Toss
