Hi, I am new to the forum but not to fly fishing or fly tying. I own 2 Down's boxes( a 5 tray and 3 Tray) and 2 Richardson's (3 Tray Ultra-lite and a 4 Tray Deluxe). Both have advantages and disadvantages. The Down's are lighter in weight and have interchangeable trays. They are also less expensive. The Richardson's are just plain CLASSIC IMO. Very high quality but are expensive. I see nothing wrong with a 4 tray Down's. 5 trays in either chest box are just too much of a good thing IMO. The box tends to get in the way. I use the front tray in ALL my boxes as a work station and a place to keep indicator's, split shot,tippet rings, etc. Good luck in your search. I think you will enjoy either box. The only time you will catch me on a stream without one of my chest boxes is when I hike and fish the small mountain streams here. Then I wear a lanyard and use a small Fishpond waist pack with a couple of conventional fly boxes.
