I had lower section last season as well. Had pretty good seats most of the time. Either section closest to the corner or the one next to it.
It would vary which side of the stadium you were on.
Best seats were second row (with no one in front of us) for the NC State game, and worst were in the pitt visitors section.
I liked the flexibility of adding seats, which I used more than once as friends visited from out of town. And it allowed me to get more people to games that otherwise would not have gone.
My only complaint is the visitors section seats. I'm planning on doing it again next year, and probably season tickets the year after that.
