Flash or PDF for tutorials

which do you prefer?

[too much information]

I am working on updating my site and I am not sure which type of instructions to put together for my subscribers. Honestly PDFs are starting to grow on me, but I'm not sure what would be easier to follow.

Would you rather have a PDF with images and explainations or a Flash movie with video and explainations?

Pop-up instructions or Flash...or both!

Flash

Flash tutorials are, well, flashy, so they might make your site look better. But for me, in the end I'd rather go through a PDF page than a flash tutorial because it's easier to pick your own pace. I always get tired of waiting for the next flash screen..

Flash or plain html instead of PDF
There are still lots of people using dial-up, many of these people may need to download a plugin to view your content. The last time I checked, the flash plugin was less than 200K while adobe's acrobat viewer was over 10M. It would be easier for visitors to leave and find content elsewhere than to wait for a 10M download.
just my 2½ cents.
