Yes, Dick & Peggy did comment a lot about hair, costumes, etc, and when they did it while a skater was performing, I found it just as annoying.
As for the volume, that's an issue with IN, and not with Tonia, Johnny, or the other guy, (sorry, I forget his name at the moment).
My own personal preference for commentators is that they speak as little as possible, while the skater is performing, and that their comments apply only to what's happening on the ice.
Save the comments about hair, funny things the skaters have said, coaching issues, etc. for before and after they skate.
I realize that others disagree with me. That's fine. It's just my opinion.
