.7 is about as slow as I ever troll, but I do cut the trolling motor on and off to trigger hits and cause the jigs to fall. I especially do this if I am trolling and troll over a ledge into deeper water I will shut it down for a second or two and let the jigs drop. If I am wanting to troll at a deeper depth I will either go to heavier jig or I usually just add a very small split-shot.
