Flyguy,
As said earlier, I'm a Richardson owner. Rain doesn't soak the contents, it gets between the trays, but doesn't get inside the lid. The trays aren't waterproof or anything, so I suppose in a real soaker they could, but it just doesn't tend to.
That said, I've slipped and taken a dunking, every fly gets soaked. Dumped the water out, tray by tray, hoping flies don't come loose from the foam. At the end of the day, open every tray like an accordian to let the air get to it, everything dried by morning. I don't have them, but you can get removable ripple foam inserts. So you can take out the insert and hang to dry, substitute different inserts, or for in the salt you can spray it down after an outing. But yeah, lack of waterproofing is one downfall of a Richardson, the other one is having to add a pouch somewhere or other for keys, shot, tippet, etc. Everything else I love.
I'd like to get a close look at a Down's system. My first impression is that the ability to add or subtract trays is really nice, and the price is better, with the downfall being they don't hold as many flies as a Richardson. But after years of vest only, I'm sold on chest boxes. No fumbling in pockets for multiple boxes. Even if let it get disorganized, looking in a new tray is just snapping open a new tray, rather than putting away a box, fumbling and finding the one I want, etc. Since flies are displayed hands free, it frees up hands too.
MKern,
I think you're right about color. I'm a matcher, I like having an exact match. But to be perfectly honest, exact color is the least important. Most important is size, 2nd most important is pattern, but color comes in a distant 3rd. For brookies, forget it, even size and pattern aren't important. Just my $.02.
