definitely below the water. In addition to keeping your hips us as was already mentioned, think of regular speed boat with a huge wave around its bow when going through the water (head out of the water) and a very smooth submarine under the surface of the water (head in the water). Which do you think has less drag?
Perhaps it's not the best comparison since the submarine goes all the time under water. Imagine if it had to appear on the surface every second (or imagine submarine swimming 50 breaststroke all out according to the rules :D ). That's right when you go each cycle under water you make more up and down movement which is very costly if you swim 50 ***. Sure you have benefit when you swim 100 - 200 event because glide phase is a longer in that case. For 50 you want lay high on the water as a speed boat. Look at the guy on the video Vladislav Bragin WR 28.47 50m br LCM Age 38 Nordic Masters 20091024 - YouTube I'm not sure he could keep his tempo so high if he had hidden his head underwater. Let me repeat, IMO it makes sense for 50 events only.
