<html> <body> <blockquote type=cite class=cite cite=""> While both are adequately capable of withstanding string tension without undoing, the single looped eye has a tendency to tighten down on the hitch pin as string tension is applied. This makes getting the eye off the hitch very difficult should you wish to twist a bass string further. The double eye, when made using an appropriate technique, will not tighten down on the hitch, and can easily be removed if necessary. I suspect that the increased friction of the second loop reduces the tension on the string knot. This, it would seem, is why the double loop doesn't lock down onto the hitch. I think it makes the double loop worth the trouble. Ron O.</blockquote> Hi Ron,                 You are right on the money re the double loops.  Several side benefits. Not least is being able to predict the length of bare wire to the start of the winding, making the start of the windings neat on bi cords and tri cords.  The double loop also reduces necking of the core wire.  We have experimented with both methods and the double loop wins hands down. regards Roger. See you soon.</body> </html>
