Get rid of the nylon line, the nylon line is visible in the water, and in my opinion thicker, therefore, giving you less feel, and takes away from the sensitivity. It kind of surprises me you are loosing fish with the nylon line it is supposed to be stronger. I would go with a common mono line, and just leave you drag loose, like I have said before a decent bluegill can make my drag scream, you never know what is going to hit, so you want to be prepared, and also sometimes your line or jig gets stuck on ice chips, with a loose drag it just peels off line rather than breaking the line or pulling the rod out of your bucket when walking along.
