Scenes=Passe?

I am working on a site that uses scenes. Is this a bad thing? I am having a hard time with scrolling text, etc.

Should I break it up into singular SWF’s? or leave it and work around that?

Will the site be faster with individual swf’s calling master MC’s vs. pages using the same MC’s?

I guess I am a little vague on the reasoning behind using scenes.

Thanks for any insight.
