By design, the one thing the Martin doesn't support that other Daedalus wheels do is Irish tension which is perfect for rewinding bobbins. There are entire blog posts about the reasons why one would want to rewind a bobbin. The primary reason is to even out twist before and after plying.
The FiberFox Rewinder takes care of that by offering an Irish-esque setup that means you can spin, ply, and rewind with the Martin.
The rewinder solution comes in a drawstring pouch that easily stores inside the Martin case and fully integrates with the Martin's on-board accessories.
A video of how to use the Rewinder can be found here.
