Make all the offhands first as they are the biggest available upgrade and only costs 3 red scrips each. For those asking what's the point of all this and not bothering because there's nothing worthwhile now... the point is to futureproof yourself for the new stuff that will come out. While everyone else plays catch-up, the crafter who prepared in advance will be making all the gil. Also, the higher your stats, the more confident you'll be in doing 2star jobs for everyone else who's willing to pay for a top-tier crafter to do the job.

The only caveat in all of this, is waiting to see what happens with Favors, but I get the feeling it won't be changing very much.
