I use the Torpedo Weighted Steel line with 19 stranded wire backing. I have three lengths that I use for silver fishing mostly. Lengths of 50, 100, and 200 feet. Basically that covers 10, 20, and 40 feet down. I can get some adjustments to those numbers with additional snap weights. It has a different movement compared to lead core and can work very well with flutter spoons. Best thing to do is get your setups and use a TD Fishawk and make your own dive charts. Hope this helps.
