I'll start by saying, I've never used a set up like this before. I assume you have a strong enough rod like a medium heavy or heavy action? A lighter action rod may not have the power needed to set the hook. The problem I see with worm hooks is they are a very fine wire. I like stronger hooks, which set nicer (but need a harder hook set) and they hold better too. Its possible pike are too strong for that setup. Its possible they can rip a hook free from their mouths before you get there. Maybe loosen up the drag? I would think you would be better off with an octopus hook. I'm not sure how big a pike minnow is, but 1/0 is usually a bit small for most pike size bait. I would try a 3/0, or even a 5/0 if bait is over about 6".
