Alas, even if I knew what he did, I wouldn't share without LFF's permission... Sorry. He has only said a) he uses the Fisher 003 pads, and b) all mods were reversible, and he shared his super comfy headband design, which is definitely worth trying. It takes the pressure point off the top of the head, and it's very easy to make.
Any chanceon a link to that famous LLF headband?
