Hi Richard-

What's wrong with wide traces? The end caps?

What about using a large element pad for your connections instead of a
polygon?

I'll have to look and see if there any facility for polygon-polygon
clearance. I've only delved into polygons a couple times, but I have a
vague recollection of something.

Thanks,
--Chad
