Creating custo post types

Hey guys,

Ive created custom posts on a wordpress theme i have developed but I find the way I do it rather in-effcient and at times buggy. Ive created all my custom posts through one function. My code is below:

/* Custom Post Types*/

/*News Post Type*/
add_action( 'init', 'create_post_type' );
function create_post_type() {
  register_post_type( 'news_article',
    array(
      'labels' => array(
        'name' => __( 'News' ),
        'singular_name' => __( 'Article' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'news_article'),
      'supports' => array('thumbnail', 'editor','title', 'excerpt', 'editor', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )

  );

  register_post_type( 'bnf',
    array(
      'labels' => array(
        'name' => __( 'Business and Finances' ),
        'singular_name' => __( 'Business and Finance' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'bnf'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

    register_post_type( 'events',
    array(
      'labels' => array(
        'name' => __( 'Events' ),
        'singular_name' => __( 'Event' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'events'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

  register_post_type( 'videos',
    array(
      'labels' => array(
        'name' => __( 'Videos' ),
        'singular_name' => __( 'Video' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'videos'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

  register_post_type( 'products',
    array(
      'labels' => array(
        'name' => __( 'Products' ),
        'singular_name' => __( 'Product' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'products'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

  register_post_type( 'sponsors',
    array(
      'labels' => array(
        'name' => __( 'Sponsors' ),
        'singular_name' => __( 'Sponsor' ),

      ),
      'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'sponsors'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

    register_post_type( 'projects',
    array(
      'labels' => array(
        'name' => __( 'Projects' ),
        'singular_name' => __( 'Project' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'projects'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

  register_post_type( 'opinions',
    array(
      'labels' => array(
        'name' => __( 'Opinions' ),
        'singular_name' => __( 'Opinion' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'opinions'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );

  register_post_type( 'tenders',
    array(
      'labels' => array(
        'name' => __( 'Tenders' ),
        'singular_name' => __( 'Tender' ),

      ),
'taxonomies' => array('category','post_tag'),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'tenders'),
      'supports' => array('thumbnail', 'editor','title', 'editor', 'excerpt', 'author', 'thumbnail',
				  					  'comments', 'revisions', 'custom-fields',),
    )
  );
    flush_rewrite_rules();
  }

Is this the best way to do it? Are there more safer and efficient ways to do it? When I switch the debugger on wordpress it doesn’t say there are errors

Thanks in advance
