i love them and use them i a boat too. they are awesome all year round. but on the ice they have to be number 4 or 5. i recently bought a set of the slab raps and if they dont commit to the rippin rap then throw a slab rap in their face right after they deny the rippin rap and they will usually get a sore mouth! and if that dont do it then the jigging rap will do them in! the only three walleye lures i use on the ice.
