cache templates in php vs using a plugin

[wpeloquin]

Not sure this is the proper forum for this question or not, but it seems like it should be. I have written a mod that has a separate php file, and multiple templates/plugins. Should the following code be in both places, or just one or the other? if the latter, which would be more ideal?

In the php file, i have the following:

// pre-cache templates used by all actions
$globaltemplates = array(
	'template1',
	'template2',
	'template3',
	'template4',
	'template5'
);

I then have the following plugin:

Hook Location: cache_templates

if ($vbulletin->options['mod_enable_global'] AND (THIS_SCRIPT=='script_name'))
	{
		$cache = array_merge($cache, array('template1', 'template2', 'template3', 'template4', 'template5'));
	}
