With paternoster, if ur holding the rod u can strike when u get a bite, and it allows you to fish multiple baits on one rig, but with running sinker, it’s designed so that the fish takes it, doesnt feel any resistance (say, a person or a sinker) and takes off. So with paternoster, its less likely to keep a fish if you leave the rod because the fish might spit it out or be more skittish.
