There are lots of tools within RDSS to select pace lines. You could compare lines using BLBL, Total Pace or even use Total Energy. Its up to the individual to decide what their comfortable with using through their own records or knowledge of the program.
For actual Past Performances I would recommend Bris PP's as their the most complete I know of and I use them to supplement the RDSS program. With a Bris account one can get them essentially for free.
