A way to present articles that may work well for you is to build a template applied to the articles folder and inherited by all documents beneath. The template would have at least one repeater that calls an all-in-one transformation. Or you could have a repeater for each element (headline, photo, body text, etc.) and then a basic transformation for the particular items.
We've done it both ways, and it wound up being easier to manage the modular template with several repeaters because the transformations grew pretty big and hard to read when revisions were needed.
The trick with applying a template in this manner is to leave Content:Path: empty in the repeater. In addition, in the Site Manager-->Development-->Document types if you select the article type you're using, you can set the default page template applied to that document type. If you leave this field blank, then you'll have flexibility to apply templates based on the content tree (as opposed to content type). Choose what works best for your situation.
Here's one approach to the content tree, templates and documents --
yoursite.com (/root) --- MASTER template with header, placeholder for content, footer
/Home - templateHome inherits MASTER; repeaters show headlines and teasers
/Home/section1 -- templateSectionOne inherits MASTER; repeaters show items from a specific category
/Home/section2 -- templateSectionTwo inherits MASTER; repeaters show items from another category.
/Articles -- templateArticles; inherits MASTER; repeater(s) displays all documents in the article folder dynamically
An alternative structure would be to have an Articles folder under each section that might inherit specific content from the parent template. The webparts can be set to display on the parent template and all children that inherit from it, or a webpart can be set to display only on the one template. So you might have an image of a widget on templateSectionOne that should display on the widget articles, and an image of a wingbat on templateSectionTwo that should display on wingbat articles.
The Kentico templates can take a bit to figure out, but it's worth the effort once you do because they can be a time saver and improve site performance.
Good luck!
