That would have been interesting, but the x-acto approach worked fine. I 
was even able to use the ohmmeter to narrow down the location - a few 
~0.2 ohm delta between the resistance at the short and a few cm away.

Anyway - all fixed now & starting to build up the board. So far so good.

Thanks to all for comments & suggestions.
