If Im fishing two lines. My dead line will be a tiny spoon with the treble removed instead six inches of 6lb flouro with a single hook and a lively minnow. The minnow will jig your spoon for you while you work your other rod. Yes they will hit right after you open the hole. I remember drilling a set on a new lake checking my depth visually after clearing the slush and start lowering my line. Not really thinking I've let out about 20 feet of line and its still going down the hole. Hold on, I'm only in about three feet of water. SET boom nice speck on the ice. Another thing we'll do is drill a set put out dead lines in 2-6 ft of water and go up on the shore for a fire and some bevs. Sometimes staying off the ice so your not making noise in such shallow water seems to be a key. Leave your spool open and use a gad type indicator though, seen many a reel go bye bye on the hit as MR Brookie drags it home
