Ok, I think I cannot give you an authoritative response here, but the
following might be useful for the labels:

either.  It assumes a lot of knowledge of the techniques used imo.

As a conclusion, I predict that this plot can easily grow to middle
complexity, and that it might be worth using PolarAxes with grid
turned off, and maybe save it as svg and remove the circle or sth like
that.  AFAIK, lines in PolarAxes are automatically bended, so the grid
shouln't be a problem (you may use some pcolor function with nans in
the values, so that only the grid is drawn)

You can override the PolarAxes locator and ticklabels.
