I stopped using the Kodak kits a few years ago and mix from scratch now thanks to Ian.

For what you are doing, stock solution might be the ticket to brighten those dull highlights, and crispen them up nicely. I assume you are leaving out the sulphide step and going straight to selenium. That said, the bleach alone at that strenght will tend warm things a little anyway.
