So messing around on Ariyala's website, it looks like I can either
  1. sink millions of gil into pentamelding my left-hand side 150 gear, or
  2. craft the craft-specific 170 LH gear for each specialist class and trimeld it.
Including my wife's main and our alts, that means crafting up each of the craft-specific 2-Star LH gears, except maybe the chest pieces (the scrip chest pieces are not bad and have 4 CP). The common 170 gear (accessories and belt) gear we already have for all four characters.

That's a lot of 2-Star crafting. It's not something we'll be able to do over a lunch break, you know?

Is this a reasonable plan, or am I just irrationally afraid of pentamelding?
