[pstricks] Strange arrow problem

Hi,

I'm working on pstricks arrows with the settings

[arrowsize=0pt 1,arrowinset=0]

in other words, arrows with heads the same width as the line, for thick 
lines.  They don't seem to be behaving properly, (see attached example). 
The blue arrows look fine, but one of the gray arrows does not appear as 
expected - it looks "overgrown", like the arrow slope is not steep enough 
to meet the line width.

Any insights as to why this is?

The minimal example:

\documentclass{minimal}

\usepackage{pstricks-add}

\newpsstyle{sflow}{arrowsize=0pt 1,arrowlength=0.4,%
   linearc=0.1,arrowinset=0}

\begin{document}

\begin{pspicture}(0,0)(10,10)
\pnode(3,7){nodeA}
\pnode(7,3){nodeB}

\pnode(3,8){nodeC}
\pnode(8,3){nodeD}

\pcangle[style=sflow,linecolor=gray,angleA=0,angleB=90,linewidth=1.2]{<->}(nodeA)(nodeB)
\pcangle[style=sflow,linecolor=blue,angleA=0,angleB=90,linewidth=0.6]{<->}(nodeC)(nodeD)

\end{pspicture}

\end{document}
