When I stack, i run my top line at least 7-10 feet above my lowest line. i then run the upper line back a little further than the bottom. this is due to being higher in the water column and gets it back away from the boat. Hard to control what the fish are going to do once hooked up. yes, i agree that the kokes usually shoot straight for the top, but if i hook up on the bottom line, i will have whoever is with me clear out the top line and clear the way. gonna have to bring it in to reset them anyway. the rod that is to the rear of the boat will always be my top line. this is what works best for me.
