I still have a Wheatley tube fly box that I use for steelhead tubes. However,I use alot of my tubes for use in the salt. For this work I prefer a Plano 3500. It has adjustable compartments to handle any length of tube fly and will hold enough patterns for a day on the beach or boat. You can also make a couple of short compartments for hooks. The Plano is all plastic (great for saltwater use), very durable and inexpensive.
Good Fishing,
