Tom;
I think the pointy shape is only an optimum supersonic shape.

Michael,
Interesting info! Is the the tear drop notion unsupported by actual
evidence? An assumption? I had heard that the best design is a diamond
and second best was a half diamond (a wedge) with the pointy thing
forward. However some of us have to go with the shape we are present
with within the rules. I like to think of my '34 as a half diamond
(wedge). Maybe it is just a 'diamond in the rough".
