I have been tying tubes (flys) for a while now. Have tied some traditional type flies, but mostly spey, and streamers for steelhead. I did come up with a design that is killer on smb and lmb. Have also tied a hopper pattern on a tube that I am looking forward to using this summer. As for carrying the tubes, I tried to use a normal fly box with ripple foam, and then long hat pins. Worked for awhile, but with all the joeling around the pins worked themselves lose. Now I just use a small clear segmented box for tubes.
