I forgot to post my results. I opted to have the rotors turned to true them up a bit, since they had enough life left. Re-installed and the pulse is gone. Go figure, I never would have (and didn't) believed the .0025" runout would cause that much of a pulse. Glad I did it because the bearings' grease seals on these rotors were starting to leak a little so I replaced them while I was at it.
Thanks to those who posted!
