A piney hop and subtle pine are two entirely different things. A piney hop would be something like Columbus or Simcoe. But 1 oz. of either used late in an IPA would be less piney than 3 oz. of Centennial or Chinook.
You not only have to know your hops' character, but also how much is needed and when to add them in order to contribute the desired flavors/aromas. Ahtanum is all funky orange spice and mild grapefruit to me. Not much pine.
