For best in slot tanking items:
Yellow=Def/Sta (avoidance) hit/sta (if under hit cap)
Blue = Sta
For OT duty when not tanking (Thadius, Saphiron, Malygos P1) get SBV set, maintain 540 def where you can be "oh shit" tank but get SBV set into play - Lavanthor talisman is must + few more SBV items, e.g. pants from Loatheb, 2xT7,5 and some more good sbv items. For any offtanking duty - get normal tanking best in slot set, gonna make life of your healers easier.
