I usually run 25 to 30 feet for kings and 30 to 50 for silvers. No particular reason other than I tend to fish deeper for kings so when the fish hits there is plenty of line out to have a nice fight and with the silvers I like to have a further back so I can play the fish alittle more (ya troll all those hours with out catching anything, when you do hook up enjoy the fight for a few minutes!).
