I don't have any direct experience with them but: The four-leaf clover design looks good as well as the box traps. I know the box traps is what some commercial guys would through in an area and get shiners. Your sport limit is 20 per day. The round minnow traps don't appear to work because they don't have big enough openings, enough space, and tend to roll if there is any water movement. Some build there own box traps or the four-leaf clover style. The commercial traps that I've seen online are $100 or more. Report back and let us know how you do.
