Loading site sections in one shot, or not?

Hey guys,

When making a flash site, is it better to load different SWFs for each section, or just make it one huge SWF?

Specifically, my portfolio section will be very image-heavy, while the other sections may be smaller in file size. Now, if people are clicking back and forth between the different sections, each click will require a “loading” screen.

If everything in the site loads up front, then once they wait for a while initially, then they can go back and forth between the sections without having to wait EVERY time…

What are your thoughts on this?

THANKS!
