While also useful for soloing on SAM (for the same reasons as NIN, you lose a bit of EVA from Resetsu but gain 6 ACC) but these aren't a horrible choice for Pentathrust builds, either.
6 accuracy in the hand slot is difficult to match (lolshura) and is only trumped by Noritsune Kote (+10acc)... which AH for about 350k more than these on Remora at the time of this post. These are still a situational piece, at best, but certainly not without their uses.
