Tanking tips for Titan (Hard Mode)

Looking some useful tips/advice for tanking Titan (Hard Mode). Have had some good practice and feel like I'm getting the hang of it, but there's one part in particular that I'm not sure of.

What position is the tank supposed to take when a bomb pops right on the tank spot along with a bomb the left and right? I've seen videos where the tank seems to just find a spot in the middle of the 2 bombs and as close to the edge of the arena as possible. is this the correct maneuver ?

Any tips to the rest of the fight as well would be appreciated. Thanks in advance.

This works for phase 1, but for phase 3, it is tougher to find that sweetspot on the outside, ask the dps where their sweet spot is, and go there.
