This is the best set for Ruinator in pretty much every situation you would use BST; don't fret about the hands, Phorcys are a very close alternative to H.gauntlets. Hecatomb+1 need 4STR on augment to beat Ferine +2.
Given that target levels are low 99% of the time on BST:
-Attack earrings do not work well; since Ruinator gives a huge attack boost, you'll always be capping.
-Moonshade earring only provides accuracy, which again, you'll almost always be capping.
-Ogiers will only beat Avant +1 on high level targets.
