Hi Burr, it is a good idea to experiment with the different surfacing tools to see what you get - and it is certainly not a bad idea for when you want a rounded tip to think of revolve or rail revolve.

You just give up some of that "down the middle of the surface" control. So it is a little different, but still for many purposes that could be fine.

The nice thing is that revolve and rail revolve tend to make a nicely formed surface throughout, including right at the tip points. They don't tend to really have the same kind of problems near the tips as other commands do, for other commands the curves tend to go through a sort of rapid changing shape near the tip there which can make for some more difficult shapes in that area.
