I do not recall the source, but I recall hearing that Chinook is highly variable depending on terroir, so you very well might be in for a treat! Please keep me posted as to your results.
I brewed with some central california chinook hops from golden state hops. They were herbal and pleasant with very little of the resinous quality that I've gotten from PNW chinooks. Bear in mind these were first year hops, so I imagine that played a large part in it.
