I usually use a K-14 kwikfish for springers in the columbia, i was wondering how deep these dive by themselves, and if it would work if you just flatlined them? Also I tried using the jet diver/Kwikfish set-up for springers with no success, but it seemed like it was difficult to reel in the jet diver. Does it even itself out when there is a fish pulling back on it, or do you have to reel in the fish, and have the jet diver pull also?
