Dunno if this is the optimized "be all end all", but I'm currently using Boarskin Himantes which are R39 exactly. Managed to find a +1 pair and they offer quite the upgrade from my Fists of the Sixth Sun.

As far as armor, I'm wearing a plain old Scouting Jacket. Eternal Shade had awesome stat buffs but the base armor itself leaves something to be desired at R39.
