2.5mph is the norn for me,attached to themain line via a swivel,about 100 or so feet behind the boat. Once ya see the rod tip starting to bend over then more than likely your digging into the bottom. Thats okay,don't panic or nothing cause your at your targeted depth. Just reel up a couple of cranks and you'll be fine. I don't use wire on the stretches,just a double line to the swivel to give me twice the protection in the event of a tail whip but its gonna eventually happen when the kings show heavy. Happy hunting.
