For MNK tanking I'm usually fulltiming capped subtle blow gear with as much counter+ as poss and have counterstance up 100%. Depending on the mob I'm /nin /war or /dnc. Having a WHM with Afflatus Solace Cure VI on hand means I really don't have to worry about much. I haven't put any attention into MDT or PDT yet, but I realise for stuns and petrify that would be a good option to save some WHM MP and avoid hate loss.
Subtle blow though for keeping the TP moves down while the rest of the party are trying to proc grellow. Since Auspice can't take Subtle Blow over the 50% cap I honestly think its better used on the nukers.
