A simple bit of stiff closed cell EVA foam, Cut to fit the inside top of the large comp in my tackle box, cut a half dozen notches in each end , and wind six rigs around it, pushing the swivel in small swivel sized holes in one end and the hooks into the foam.
I rareley of ever use more than 3 hooklengths in a session, so thats plenty, one long and one short of each , hair rigs with captive bait stop, Hair rig with bait bands and Hair rig with plain hair loop. The hooklengths sometimes are a bit kinked by having been wound around the foam board but a quick stretch of the mono straightens them out, I never ever use braid so it doesnt come into the equation .
I also carry a spool of hooklength mono and a small box with various sized hooks so I can make up any different hooklengths to order as needed.
I hate the plastic "envelopes " as every hooklength seems to end up in a taffle, no time for rig boards, they take up too much room in my bag, and the pins get lost, I use something similar to the Guru rig winders that Cliff mentions, but only for my beach rigs.
