In my case it's a new project (Word Web Add-In), so the option of supporting both SWF and JS is not an issue. Will never be necessary to support SWF. On another project that I have and it will resume very soon, I'm rewriting a whole SWF project to JS and the goal it's to forget SWF after that for good. So I will stick to the Map option.
