Why do I get twist knots in my line when casting my spinning outfit? It happens on almost all of my open-face spinning reels, regardless of who put the line on, how much line is on, what type of line it has. BTW - it is not from line coming off the reel against the drag either. I let the line drag behind the boat to let it untwist, which works, but after a couple of hours of casting, it happens again.
