i use a rapalla soft bag with 4, goin on 5 plastic trays and bag has lots of pouches as well for extras,can even stuff a sandwich or 2 in there with some tp

each tray has removeable dividers so u can set each tray up for different size and length if equipment
i have everything from sturgeon to fly fishing in one bag but when it comes to fly fishing i usually leave bag in truck and take vest with many pockets unless i know im gonna be changing back and forth from gear to fly ,but bag is still good for packin as it has an adjustable strap to throw over shoulder and do the tour
