FA, Quasi, Alltimers - mainly to sell to the younger demographic of teens through dudes in their mid 20's
Santa Cruz, Primitive - basically for people who cruise through the shop but don't skate/peeps that will buy a complete once and thats it, but actual skaters will buy these from time to time as well
Krooked, Chocolate, Toy Machine, Baker - long-time board brands that everyone generally likes/will appreciate. also just seems right to have a little representation from each distro.
last brand would probably alternate between Western Edition, Isle, and Magenta more so for my personal taste
didn't think it would take that much thought trying to narrow it down to 10 brands sheesh
