I'm hoping someone with Solidworks flow simulation can run a simple experiment for us. Create a rough tear drop. Say 2 feet max diameter and 10 feet long. Round in the front and straight sides tapering back will work if it makes it easier to create the shape without the complex curves. Compare the performance of that with the same shape that has been cut off flat on the front at 80% of the radius. And to a shape with the round front but a straight cylinder all the way back to a flat back. And finally, to the original best shape that is truncated at 60% of the length with a flat back.
