I have played with it last year and had similar. A 30lber gave me 3 bleeps on my delks (at 4+ setting) and that was all. Next I knew I had hooked a fish was when my other two rods ripped off as it ploughed through my lines. Long, stressful fight later I managed to land it in the pitch black and freezing conditions.
Few other odd occurrences. Can't beat the running rig IMO unless you need to use the heli for deep silt or weed.
