I got me some Hawaii schools at D1. I've found the best recruiting tactic is sacrificing chickens in honor of the random number generator being. But yeah, basically go for Internationals, get every serviceable hawaiin, and pray. IF, and that's a big IF, you recruit in North America, I would say stay out of Pac-12 area cuz you need them to do good to get the money to recruit Internationals. Honestly though, it doesn't matter since you can't battle in N. America and must wait and sort through the scraps.
With patience and luck you can get to a steady B+. I've only lost 1 battle for a hawaiin and that was my C+ prestige vs. a Big East A+ school. That was a major set back since so much of Hawaii recruiting is just hoping for great local talent.
My last bit of advice about N. American recruiting is try not to go incontinent!
