I recently bought the SA streamer slit foam box but at only 4x6" roughly it does not hold the flies i want to put in it.It says it will hold 72 flies but with me putting size 10 poppers with rubber legs 15 flies on one side carefully placed is all i can get on one side.The other side has #10 clousers and bead chain eye dragon nymphs which hold a little more.I have a camo waist pack i like to strap on that will hold up to a size 12" plano type box that i am thinking of using.I can place similiar flies in the compartments with out damage.What does everyone else use?
