King Arthur Bread Flour KABF does tend to make bready pizzas, so your inclination to try another flour is a good one, it's just that 00 flours are not ideal for a NY style setting. If you want to step up your NY style pizzamaking game, I would suggest finding a bromated 14% protein flour such as All Trumps. Restaurant Depot usually carries All Trumps:
945 N Hayden Meadows Drive
Portland, OR 97217
Phone: 503 283-1200
Fax: 503 283-1300
They're only open to businesses, but will sometimes give individuals one day passes.
I'm sure there's other flour distributors in the PDX area if restaurant depot doesn't pan out.
