I want to use a completely different single.php template (which uses a different header, footer and css file) for one category within a custom post type. This custom post type already has a single.php template separate from the rest of the site. I tried a category template, but I think because the posts in this category are also included in other categories, I'm not getting the results I want. Taxonomy doesn't really seem to fit the situation, so I'm not sure how to do this. Advice? Thanks.
