I got a tip from Roman, one of the guys at Marmish, for setting the hook. He suggested dropping the tip of the rod down slightly before setting the hook....kinda like a scooping motion. Imagine your rod tip at 90 degrees from the ice (perpendicular), then dropping the tip toward the ice while lifting your wrist up at the same time.
I've been using this method this year, and my hookups have been really good.
