How should I set up my new Priority Bruzer?

I am about to have two bikes for bikepacking:

–Priority 600x with 29×2.6 tires: this is my rig for singletrack heavy trips. It works great for rugged singletrack but moves very slow on pavement and flat dirt roads

–Priority Bruzer: the Bruzer is going to be my bike for trips that are mostly routed on smooth dirt roads, gravel, pavement and maybe some singletrack. I want to ensure it's as fast moving as possible.

I was thinking about setting it up with 29×2.25 tires, frame bag, handlebar bag and seatpost bag. I would love to hear any other recommendations? I've only ever ridden 29×2.6 tires on my bikepacking trips so I definitely want a faster rolling tire!
