I would recommend these for any DRK/THF above lvl 60. They are great to have to sub in for Sata Skillchain as they add strength, and accuracy is greatly enhanced from the sata itself. I use them on my own DRK together with a bomb core which adds a nice little extra damage.
there is no Dex or Agi modifiers to SATA when Subbing Thf, So any /thf would do much better with gear that directly raises the modifiers to the WS they are currently using, or Atk gloves.
As a Thf, I'd rather use Tarasque Mitts+1 over any gear available that I've seen anyway. And yes, I know these aren't Thf equippable, I'd probably use TM+1 over these anyway.
These are ok but it would be better to use one of the Gigas bracelets, either Ogy, Enky, Pallas or Alky. They have better Str bonuses in spite of the Dex and Agi minus.
