When I ran the 480s, I always liked the 63's on the end unless I was outside. I rarely tape indoors in a good sounding room, so the 63's pretty much stayed on the ends. Before I got the 63s, I would run the 61's XY in bad sounding rooms, and I liked the results. Lots of folks will disagree with running the cards XY, but for me and my playback system at that time, that is what pleased me the most. If I was moving back to the AKG's and had to chose one cap, I'd go with the 63s, but only because of my general taping circumstances.
