I used ztto ones that are hollowed out and they fit RD13 hub which is what you probably have in your edge wheelset.
I used same ratchets on my yuanan(elite), xmcs and tagoola wheels which also have cross compatible freehubs. I don't think hollow/solid ratched matters as long as you use the provided springs.
Make sure you are buying ratchet with 2 springs since a newer dt swiss design (ratchet exp) has only one with the other ratchet screwed into the hub shell
