A friend of mine wanted to spend an hour or so trolling for walleye a couple of weeks ago. We had been fishing for bass and I had a bama tied on so it threw it out while he trolled a crank. Mine aren't weighted except for the baits which had 1/8 oz heads on the three of them. The bama became a topwater bait. I couldn't keep it down at all. It might work if you could get it to stay down a ways.
Earlier in the year when it was working on bass, I also caught some walleye on it but that was weeks and weeks ago.
