If you have line twist and don't want to drag the line behind the boat or don't have a boat...... connect a quality bearing swivel to a post, tree or other. Tie the line to the swivel and use your rod. Open the bail and walk off 10 to 20 yards beyond a max casting distance. Slowly reel yourself back to the swivel, watching the to see the swivel is spinning. Maintain some tension. This should remove the existing twist or at least 90 percent. It works pretty well.
