I wouldn't change a thing... Keep it tight! Are the twists causing a problem? When I make endless loop strings and use a jig it twists every time. The cover serving is what causes mine. As the spooled jig passes each string a slight amount of twist goes in each one. when I take it off the jig the loop tries to reverse twist. But as I said before it always comes out later. I'd rather stay on the tight side...
If you look closely you can see the strings under the cover serving already beginning to twist caused from the friction of the serving spool jig.
