I think i'm going to park my lvl 150 "sloob" fixer where he is until I get him completely twinked. I never want to upgrade my account from "sloob" because of how unique it is.

What is the best prof to start on my froob account to start levling with the intention of becoming fully paid as soon as he is high level? Is it true that agents can sort of act as a buffer since they can shape-shift into any prof for a short time?

Is it better for me to level like an NT to PL future characters on my "sloob" account?
