Flies officially become lures under five conditions:

1. More than four pairs of treble hooks.

2. Their weight makes them impossible to cast even with a #12 weight rod and matching Clouser line

3. They cause invading BASS anglers to back off their boats when you fling one in their direction.

4. Every fish in a two mile radius flees when the fly/lure hits the water

5. When every single member of FAOL agrees that it's a lure

Hope this helps clarify the distinction. 8T
