If some one made a Wheatley style fly box that was 2" deep by 4 1/2" wide and 7 1/2" long, rippled foam on one side and compartments on the other, I could get by with only ONE fly box. I fish dry's 80% of the time so my concentration would lie there. I almost never fish streamers but have a small perrine streamer box that I could also carry.

As it is, I usually carry 3-4 boxes with no particular organizing other than putting flies into the box that they best fit.

P.S. For mountain stream brookies, a large fly patch would do the trick!
