[itlnherq] Elegant 17-pointed star

Gauss wanted a heptadecagon inscribed on his tombstone.  However, a heptadecagon looks too similar to a circle.  Better would be a 17 pointed star (as was done at the Gauss Memorial Monument at 52.27196,10.522647).

Of all the 17-pointed stars that can be formed by connecting non-adjacent vertices, which is the most elegant?  Not too spiky, not too round.
