If you see a musky following your lure; don't slow down, jerk the rod a speed up. Most folks slow down on a follow, in the real world, bait will do everything and anything to get away. Don't forget to do the figure 8 at boat side. Often time, the musky will follow from below the lure - you won't know she's there until she comes up on the 8. It's an awsome sight to see a mid 40" torpedo coming toward your lure! 70% of muskies caught come on the figure 8..
Good luck.
