My favorite is under tramp storage. You sew the "bag" to the bottom of the tramp and add a zipper to the tramp to access it. 3 to 4 inchs deep seems to work.

I like to divide mine into 3 sections. A zippered bag on each side of the center and a small tight pouch accessible from under the tramp for the righting line.

Even if you do not like the zippered idea. A tight pouch just for the righting line (and maybe the throwable) under the tramp really cleans things up and is worth the effort.
