"the fact that the 'new lure' worked better than your pellet fly is proof that your fish aren't eating your pellets as aggressively as they once were."

I actually think there are two reasons the 'new lure' (pellet) worked better than the pellet fly.

1. George's wife was using the new pellets....hehe
2. The new pellet is quite frankly better than the pellet fly. The new pellet gives off more pellet scent and looks more natural than the pellet fly. It has nothing to do with conditioning. The fish were not feeding aggressively due to the weather conditions present.
