You won't be sorry you take such good care of your bike!
Lube choice really depends on the conditions you ride. I used White Lightning when I was riding in the midwest, and it worked great there in the sand and thunderstorms and baking heat.
Here at home (Seattle) I use Boeshield, which is lovely in our chilly damp and drizzly squelchy fine-particle-and-biomass muddy environment.
Enjoy your clean drivetrain!
