Although I don't use em, since I don't fish pike in the winter, I am still familiar with them. The length between hooks depends on the length of your bait. Obviously, you couldn't seperate the hooks by 8 inches if you were using 4 inch minnows, but it wouldn't be very effective to seperate them by 4 inches if you were using 12 inch baits. I've seen some that use an adjustable hook, so they can be adapted to various size bait. Sorry, but I don't recall how they attached the sliding hook, I'll see if I can find that though. Hope that helps a little.
