Have you seen the effects of not using any other h tags on your site besides the h1?
In my experience, I've seen the opposite. Well done h2s in fact, can really boost a series of site's rankings.

No doubt your page also can get ranked using the normal h- hierarchy.
The point of this technique is to put as much value on the main keyword as possible. Make it really obvious to the search engines what your page is about. Your page may have other requirements, so use accordingly.
