I asked this question a week ago and got no help.I guess we missed this topic when it came up earlier this year.I have found some info go to www.lakemichiganangler.com on their home page is a column click on tips and techniques & you will find dodgers.As far as which end to rig I would say that the swivel goes to your lure so you can change up lures without retying. Both ends of the dodger are shaped the same. good luck & check out the site lots of info.

There is a small rudder on the rear of the dodger, that is the end you tie the flie, etc. the other end to you line.

We usually tie a fly or streamer on 10-12" behind with mono leader.

Hey Wayne..

The end with the snap swivel is where you tie your flie or lure on too.. or smelt.. depending.. You can run short leaders.. 10-12 inch or longer leaders.. 18-24 inchs.. depending on your trolling speed and your desired bait.. There are lots of ways to rig them.. I like them with a Pauls Bait Rig and a dead smelt.. works great..
