First I try bouncing it up and down to loosen it a little if I can. Then I troll one way for several feet and try to drag it out, then back the other way. Keep trying this in several directions, but always go straight back across to the center before changing because you surely dont wanna wrap the rope. This has worked for me many times but it might have just been alot of luck. Its not a proven method, but I have been lucky.
