Files/Folders or learning Modules?

I'm close to having two demonstration units ready fro staff to look at. The key difference is that one uses a folder to deliver each weeks entry and the other uses a Learning Module. As I have worked on this I am beginning to get an insight into the different approaches. Overall Vista is a frustrating tool to use as a. it's new to me and b. it has limited functionality, especially when you work in the copy, cut and paste made of a web developer.

So which method is best? I'm not yet sure! Creating a folder I use the header to provide the title for that weeks entry, plus additional text such as learning outcomes for that week. Everything else is attached below as a file. This allows me to attach to lecture slides and handouts. Using the relevant icon (MSWord or Powerpoint) it's easy to warn users of the file type. It's also a good way to add external web links as they get gathered together under the WebLinks button on the left.
Entry for staff is fairly simple, they can use the HTML editor (in WYSIWYG mode) to add/edit text to each weeks entry. Linking to files is also simple. This is either files already uploaded or files held locally to be uploaded. Staff would need to follow a convention for naming files and finding the correct icon.
Likewise, linking to existing learning modules from any week is straight forward and requires little skill or knowledge.
There are possibilities for use of webdav, which for the uninitiated gives you a folder on your PC desktop that links straight to your units files. This allows you drag and drop access to your unit files. You can also do this from home with broadband.

The big issue for me in the above method is you are obviously using the folder in a way it wasn't designed for. By using the header for what is essentially the body text you are bending the application to our needs. This means it's not as flexible as you would wish. However, it does provide a clear interface to the weekly entry and it is relatively easy to maintain.

Using the Learning Module method to supply a weekly entry is not dissimilar. However, the 'body' text is created in its own HTML file (which we can pre-prepare and label) which is much better than using the header. The module is designed to deliver a series of files, one after the other via a left navigation menu. We would be using this menu to serve up all the additional documents and links.
The down side of this is that we will need to flag up at least the file format in the name we give the link. In Courseware we ensured the system tagged up any file to disclose both its file type and file size automatically. In either way with WebCT we will have to do this manually.
By serving up our supporting files from this menu (eg. Powerpoint lecture slides) we are breaking the model of the Learning Module. When students get to use an actual Learning Module they will find that the menu usually contains a sequential series of web pages as they work through the module. Are we going to cause problems by breaking this model?

Thoughts and input from others facing these issues would be gratefully received!
