PvP Tank Gemming in 5.3

With the resil gems being reduced 50% Would it now be smartest for tanks to go hybrid gems like the following:

Main stat+stam and Main stat+dodge

or pure main stat in red slots? (Agi is a nice stat for bears like me, but having rediculous sta might be a nice buffer.

Or is the % of resil we will still be able to get from gemming straight resil still out-weigh the gems above even after the 50% value reduction?

Thanks for any ideas/conjecture in advance.
