This body piece is much more difficult to selectively augment for melee jobs that have no particular specialization such as THF & MNK, as they have a wide spectrum of body armor that cover most if not all bases relating to their various purposes or play styles. However, the initial bonus of 5 STR, 5 DEX, 5 AGI, decent defense and HP & MP is nothing to sneeze at and the additional augments can easily match or surpass many pieces that already exist saving you alot of time, effort and/or gil.
Here are a few examples of body armor pieces that cover most bases for THF:
Homam Corazza
Enkidu's Harness
Dragon Harness
Rapparee Harness
Hecatomb Harness
Alternatively you can simply get a freebie watered down Skadi's Cuirie or Antares Harness
