Nancy,
This is a tough question.
From all the reading I have done and seen, world class swimmers keep their heads low in the water. I cannot speak for their line of sight.
You might sacrifice a bit of fore-aft aligment by looking slightly forward but it is so worth it when learning to find your hands and arms.
I do a tremendous amount of swimming with a center snorkel where I never move my head. I use my periferal vision to locate my hands as I swim. I kep my head in a neutral position.
