kotz,
Looks like we need to get an article in there and fast right?
We will see what we can do here. Welcome to the site and I hope you find it helpful as everyone else does.
First off, this has been a hot topic for the last year or so on the board. Using the powerful search tool that we have at the top of the page would be a great starters to find everything discussed about ringworms…rigging, techniques, locations, depths, etc…
Ringworms are incredibly universal tool for walleyes on the rivers. Some people are having great luck vertical jigging them in waters as deep as 30+ feet. Pitching them on light jigheads has been very good for bigger fish in shallower water. The slow drop speed of the ringworm coupled with a light jighead is deadly for triggering cold water walleyes. Pitching these ringworms can also be fished in depths ranging from 2-30ft of water just by adjusting jig weights to accomodate the situations.
I know this is a very general answer for your question and I think we need to get an article up to explain all this in more detail soon.
Look for an FTR video to be out very soon on the “how to’s” to fish these ringworms. This will be a great way to learn all your ringworm techniques aswell as answer all your questions!
You will get lots of responses here on this post as this is a very hot technique on the river right now!
