I use the small size Plano fly box (3582), because that fits in a shirt pocket. I replaced the foam with special order ice fishing lure inserts from Rose Creek on both sides. Since I normally only use 32nd oz and smaller heads (plus a couple of 1/16 oz just in case) on hooks size 4 on down, that gives me some four dozen or so jig heads of various styles and sizes. I store spare heads in a separate, much larger Plano box by themselves and keep it dry. I usually stick with black jig heads, regardless of the plastic tail; so I don't need a huge selection. This fits in a shirt pocket, real handy, and unlike foam mounting the hooks don't tear up the mounting and it has not needed replacing for some years now.
