When I'm tanking, first and foremost I'm in commander mode, with my head and torso up out of the turret. Tanking with a mouse becomes an inherent advantage when you can swipe the mouse right to get the turret slewing right, go immediately to mouse pan with a toggle on your mouse, and then quickly look around in all the other directions as your turret is still slewing from your first move.
I also do the same things Jinx does. I do find it easier for me also, but that is what I am used to. I suggest you try our method and see what works best fugi.
