The Mustad you mentioned is the light wire one you are looking for. I would suggest you try the Eagle Claw one as well. The Gamakatsu he uses is a custom hook and the only way you can get them is buy 50k of them.
I would say good luck communicating with them. Sent them 5 emails and only received one reply so far. I ask about having some Hole-In-One skirts made in non stock colors and just received a link to their web page.
