The new tubes arrived today from TAP plastics and are everything that I wanted. Enclosed is a picture of the new tube next to the old tube that came with the Fishpond Coyote bag. I have replaced the hook boxes in that bag with these from Craft Mates and now the tubes and I have something that works. http://www.craftmates.com/locking.html
For a bag that retails at $180 the hook boxes and tubes sucked.
