Using a custom view for a taxonomy term page Using Drupal 7 and Views 7.x-3.0-beta3, what is the best way to have a taxonomy page use a custom view?

For example, in Path Auto I have a rule that points the URL alias countries/england towards taxonomy/term/44.

When a user visits countries/england I want to display a page created with Views, not the default taxonomy page.

I am populating the menu using Taxonomy Menu which doesn't yet support custom paths in Drupal 7.
Maybe I am misunderstanding what you are saying, but Views comes with a view for taxonomy/term/%tid. Once enabled, when you visit http://example.com/taxonomy/term/44, Views will show its own page, and not the default page output from Drupal.
