Well, the way we used to fish it was pretty close to using downriggers. There are some bars up further down where the water would move pretty good, and we'd use up to 8 or 10 oz's of lead to hold in 15 feet of water. This was for fall fish, now, but I'm imagining the same stuff will work for the springers.

We also used to pick up springers when trolling for walleye, so I've got a hip pocket strategy if necessary.
