What pick thickness gives a jangly, airy strumming sound?

A thin pick like a Dunlop Tortex .73mm (the yellow one) gives a loose, airy strum. It bends on the strum, producing a softer attack and more string noise, letting the strings ring out with a breathy, jangly quality. A thicker pick would give a punchier, more aggressive sound that would kill that vibe.
