Want opinion on loading multiple FLV's so they play in sequence

I am creating a rather long bit of advertising animation (currently about 2500 frames at 30fps) for a client and am using a combination of content created via AS3 as well as an FLV I’ve created in After Effects. I have embedded cue point events in the AE file.

There is a small, ribbon like thread that undulates across the screen throughout the whole animation, but other than that the FLV is basically 10 discrete segments, fading in and out to white between segments.

I am wondering what is the best way to build my swf for delivery. Currently, I have one gigantic FLV that I am loading via AS3. Added content (text and graphics) are created dynamically with scripting and are triggered by the aforementioned cue points.

One issue from a production perspective is that any creative changes requires a rerender in After Effects, which can take hours. But this isn’t a huge issue.

What I am wondering is should I just create the one huge FLV and call it a day, or should I perhaps cut the segments into smaller chunks to make load times faster.

I am fairly new to Flash and AS3, and have not yet got a handle on the whole load time thing.

One conditional for going the multiple FLV route is that after each FLV ends, the next one needs to be there, ready to take the previous FLV’s place. Because of the undulating ribbon mentioned earlier, it’s important that there not be a pause between player instances. Is that even possible?

Sorry for such a long post. I just want to be thorough.
