Ok, I've read as many "how-to's" as I can and got my plan worked out on how i'm gonna make them. Now my question is using them. With the flagging type, I'm kinda thinking these have to be set up anchored, correct? Also...When using live bait(bluegills), can the bluegills "jerk" them hard enough to "flag" the "jug"? Any tips here would be great. Thanks!
