What is the best way to create a complete site in flash?

[FONT=Calibri][SIZE=3]I have made four complete flash sites and I’m about to create the fifth one, but every time I start creating a new one I get into a debate myself on what would be the better way to create the site with all its different sections (home, contact, about, etc… ).[/SIZE][/FONT]

[FONT=Calibri][SIZE=3]Should I create all sections in one .swf file or shoud I create .swf files for each section and load them as needed?[/SIZE][/FONT]

[FONT=Calibri][SIZE=3]Can someone share their experiences and tell me the most efficient or common way. [/SIZE][/FONT]
[FONT=Calibri][SIZE=3]I’m using 70% actionscript 3.0 and 30% flash for the animations.[/SIZE][/FONT]
