Line can also become twisted from a fish pulling out line against the drag.
These are known ways to get line twist. Test Data Test data in comparing ordinary spinning reels to the Twist Buster System was done by simulating fishing conditions under Daiwa's standards, i.e. bait fishing, lure fishing and surf.
