Architect Archive

Well as most people I have started working on holo (becauseI need a new goal in this game) so now on my 3rd holocron I get Architects (the once before was brawler and marksman.. and thats not much of a goal)

I just wonder, what should I craft the get the most use out of my resources?
My friends says Wall Modules, but since I need 10 identical structural Modules... im not sure if its the best.. Just don't want to waste the few resources I got.
