I Also use the quick strike (double trebel hook) rigs for pike fishing. I make my own, and the leader material is the sevenstrand wire - I use the 20# material I think. It is very thin, fairly flexible, and no bite offs. I don't fish too often for walleyes, but did manage to accidentally catch a walleye on one of my tipus with this rig on a 4" shiner after dark. As to the live shiner/dead shiner debate, I always catch more pike on a lively shiner. If they are dead or sluggish, I really don't seem to get many flags. I think it might have to do with the minnow trying to get away from the pike when it comes into striking range - predator response. With the double hook, I put the terminal hook behing the minnow head, and the sliding upper hook 1/2 way between the tailand the dorsal fin - keeps them swimming like they are injured. An inline spinner with blood red reflective tape also works well for me. Good luck.
