Overall I think there is a consensus of concentrating efforts on the tail, not the nose.

Pressure drag
Pressure drag is caused by the air particles being more compressed (pushed together) on the front-facing surfaces and more spaced out on the back surfaces. This is caused when the layers of air separate away from the surface and begin to swirl – this is called turbulent flow. Note how the wing shape reduces this.
