I have been doing this a lot as of late. I would recomend US04 and 1968. The 1968 brings up the point of diacetyl rests. I think this is important to bring up when talking about rushing things. 24 or 36 hours at or just below 70f after primary is complete can finish a beer up quickly and quite nice. I try to get all my hefes in the keg before 7 days, i think it is the secret ingredient! I also think IBUs amd hop oil contents play a big role in a beer tasting green. I have found any thing over 50 or so IBUs to require a month to come around.
