507 19" Tire Question

1. Buy another rear set of the ConstiSport 255/30 rear tires.
2. Buy some PSS (or RE11) 265/30 or 275/30. I don't like the idea of having mismatched tires, but would like some extra width in the rear. What do others think?
I also noticed that the Contis weight less than Yoko, PSS, or RE11 in any given size how much will this matter?
