I'm looking to level a Tanker, but have a few to consider, and am looking for assistance. 
  
I'm torn between Willpower, shield, Ice, and Invul.  Each of the four have their proc and cons, but what I was seeking was actual numbers for defenses/resistances to each. 
  
I was linked a decently geared Io Shield Tanker (Pretty tough looking: 15% defenses to everything on top of 44% positional defenses, along with 90% Lethal/Smashing - 55% the rest)

The others I do not have the numbers for (With IOs of course), and if anyone can help me there, I would be grateful.
