I am curious why this technique wouldnt work. Most downriggers that i know and i am not an expert but i believe release the line when there is a strike. Plus you can use monster weights without blowing out your shoulder realing up the huge weights on your line. WE have been talking about this on our last halibut trip on the way home from deep creek and wondered why would this not work. I think this would work great especially if you are slowly moving against an out going current, you have a downrigger bouncing baits off the bottom. I would think this would be magical for halibut.
