I agree. I also find in open water that because there is no sense of speed as there are no tiles you have to just think about rhythm and timing. My current wetsuit is far too buoyant though. It makes me feel unbalanced around the hips and legs and I can feel my feet coming out the water often. I have a new Huub wetsuit which is much better but it seems to be made of tissue paper. It's so fragile! I don't like the zip either.
As it turns out, in open water I don't swim straight! In the pool I must make subtle sub-conscious corrections. I only breathe to one side though so that might have something to do with it.
