THE FIX Imagine you have a tomato stuck on the end of a stick, and you want to fling that tomato into a bucket, say, 20 feet away. How do you do it? If you "whip" the stick, you'll end up splattered with red mush. But if you gradually fling the tomato off the stick, you might get it there. Same deal and same feel with the fly cast. The motion must be a gradual, controlled acceleration to an abrupt stop.
