I have level wind trolling reels, the whole reel is filled with the lead core, it works good for me, you can tell by the number of colors how much line you have out, and get acurate on how deep your fishing. The line does cost but will last multiple years. If you can I would put in on reels and leave it on, larger spinning reels will work too, but level wind are better. I use this for suspended fish and fish close to the bottom, I don't think this will be better for walleyes hugging the bottom though, I would stay with the Lindy rig. Have caught suspended walleyes trolling crank baits, like HotN tots, etc..
