Finally signed up. I started ice fishing last year and I am as crazy as the rest of you now. Can't wait to get out there. Anyways, what is the rule of thumb for leader strength compared to the biggest fish that you may catch in a body of water. If the biggest fish weighs 20 lbs would you use a 20 lb leader? Is the rule pound for pound or something else. I would not want to lose the big one however getting by with a smaller leader would be stealthier. I was all mono last year and will be fluoro this coming year. Thanks
