Bill? Shall we use the Hartzel design?

I'm on hold pending airfoils from Bill Freeman.  I've given
up on copying the Hartzel planform since we have about twice
the twist in degrees.  It's harder to keep the straight trailing
edge, probably no need to.

I think we would lose little by going with a straight taper.
I wonder why we have twice the twist. The P210 is a 200 MPH airplane.
