Lip Syncing Tips

I have a Character that does a full turnaround, this character has mouths for the front view, quarter front view, side view, and quarterback view, how would you lip sync this? would you use the auto lip sync, using only one view and correct over it, or would you manually go through and set the mouths to the audio track as it goes along, would you split the audio clip up by viewpoints and run auto lipsync over each clip and setting it up with whatever mouth set it needs to be mapped to? what would be the most time efficient way to go about this? I know it will take time but I need a pro tip on this one thanks!
