Hi Michael,
It seems my last email to you bounced (though it clearly got to the list).
Anyway, you might want to try removing the lines:
</FeatureTypeStyle>
<FeatureTypeStyle>
By using those, you're asking GeoServer to draw the lines on separate
rendering passes. In reality you want them done on the same pass.
Regards,
Jonathan
