When designing a jig, you have to build it around the hook. And if your not a hook manufacturer, you're pretty well stuck with what's out there. The only way to get Owner or Gamakatsu to make a new style is to have a contract that promises you will buy an ungodly amount of hooks from them. I'm pretty sure Nutech was stuck with the closest thing to the ideal hook they could find. They have since come out with extremely good quality hooks. I'm not a pro staffer or have no agenda.
