I have used them for catching Walleye in Lake Erie. We used them for flat lining behind the boat , and didn't use a snubber , therefore we ran 20 lb mono. They will take your line out to the side of the boat as advertised. I think that we may have set the release tension too high because we couldn't always get them to release properly and when this happens it's a real chore to retrieve them. Best of luck.
