350STR is the WS stat cap for hand-to-hand weapons with a 131 damage rating (Ifrit's Claws exclusively, at this point).
This means each point of STR, up to a maximum of 350, provides its full bonus to the damage calculation of WSs. After 350, it still provides a bonus, but at a reduced rate due to the derivation of ATK (unlisted in the equip screen) at a rate of 3STR:2ATK.
INT is similarly capped at 310 for WS, though without the benefit of virtual ATK.

If you obsessively monitor your ST recast and always have a target available to take advantage of that reduced recast, you might be able to make a case for it in terms of burst damage and TP gain. Maybe. In a particularly long fight.Quote:
General consensus is that AF legs for lower tackle recast just aren't worth it I assume?
Note that it would take a full 10 minutes of spot-on ST usage to get in one "extra," and if ST slips your mind or is inconvenient to use for even 6 seconds, the bonus is wasted.
I would not recommend wearing it for the recast bonus, but for leg gear it has decent stats (and it is, more importantly, free).
