I never use a sinking line when night fishing. I weight the shanks of the flies with lead wire. I put the different weighted flies in various Zip Lock bags in order to keep them organized and reduce bulk. I do not wear a vest when night fishing. My gear consists of 3 Zip Lock bags, a few spools of leader material, 1 fly box, a camera, and headlamp. Make sure to get a really nice one as the inexpensive ones tend to break after a short period of time.
