TEPaul,
At one time, when I thought it might make sense to add a replicate bunker further out, I knew the exact carries for each of those bunkers.
The right side of the fairway has a slight cant, the cant increases as you move toward the left rough.
You question on the approach depends on the golfer.
Some prefer visibility, so, for them the right side, where the green and alley of approach is more visible, might be better for them.
Shorter hitters are probably better off on the right side, if they can get there because their approach can be lower, or along the ground, whereas an approach from the left must have a significant aerial component.
My recollection, not to be counted on today, is that the forward right bunkers are in the rough and gradually emerge from the rough as you move away from the tee.
