[R-390] Orange Drop vs ceramic disc

[Cecil Acuff]

I think it's important to also mention...there are two different type of 
Orange Drop caps.  Can't remember the designations without the catalog in 
front of me but...there are.  I think one is metalized film and the other 
film/foil types....am I off track here?

We need to make sure we don't direct folks using the Orange Drop terminology 
in a blanket fashion.  As I remember one is recommended and the other not so 
much.

I'll have to pull the catalog to fill in the blanks if someone else doesn't 
chime in...
