Graphics, Figures & Tables ⇒ pgf: wide arrows with borders, ugly arrow tips

[laughingrice]

I'm trying to draw a wide arrow with pgf in latex with a green color and black border using

\path (0,0) coordinate (A)
(0,2) coordinate (B);
\draw[->,draw=black,double=green,line width=1pt,double distance=7pt,line cap=round] (A) -- (B);

The arrow body comes out great, juts as I want, green inside and black border. The problem is that the arrow head is all black instead of matching the body.

Is there a way to achieve this? I don't care about what arrow head is used, just as long as it matches the same style of green inside and black border.

I tried looking at the arrows library but it's good for drawing arrows but not connecting points as far as I can tell.
