grimace has it about bang on mike ,i run leadcore 17lb with a 50ft leadeer,or i will run trilene big game 10lb with a 20ft floro leader,if you want to run husky jerks or any baits that dont dive much at all the core is the way to go,its deadly i have done very well with both set-ups just make sure you follow the trolling bible line size guide,and the speed,and the line out on your line counter reels,its about as deadly as it gets man. !!! see precision anglers guide its the bible for us walleye guys...cheers
