I don’t know of any body who runs dodger backwards for any improvement in action. The dodgers are symmetrical in shape, I would think that they would run about the same in either direction. If you tie a loop on your leader for the flies or lures, you can then change them easily, the corkscrew aids the change of flies or lures easily, some dodgers come with snapes. I have a fly book that contains flies tied up with leaders with a loop ready to go.
that is exactly the reason for the CORKSCREW so you can change your lures and flies much more quicker by just wrapping the loop or eyelet of the lure or leader. much faster than opening and closing a swivel, and it won't open up on you.happy fishing.
