Bonus- you can change the 36t ring to an Ultegra 34t ring for about $12 off ebay.
So you get a bit smaller ring in the front, you retain the quick shifts of the tight ring difference, and you can get away with a slightly smaller cassette if possible(depends on the user, obviously).
46/34 is what I use and love it for the fast shifts(among other things).
