You dont want a "double metallized" capacitor, the peak current ratings 
will be lower than a metallized with foil capacitor.  The pig will 
certianly eat those up ;)  You would be better off buying the well known 
942C series cornell dubilier caps.  They come in similar values, and i bet 
they are much cheaper than anything from Digikey :o)  Though, the idea of 
10 strings is good.
