Personally I just aim for pyros weapons to have stat at least on par for its item level. A suzaku sword with melds considered would have 481 secondaries, so I'd settle for around 500 on the pld pyros swords with Crit being most desirable and Ten least desirable. Det and SkS are nice too; I'm not sure if the random stat generator gives any DH for the tank/heal weapons, I think it only picks from 4 potential stats for each job.
