Gravity form enqueue scripts in functions.php vs. head.php

Reading http://www.gravityhelp.com/documentation/page/Gravity_form_enqueue_scripts, it says to place the gravity_form_enqueue_scripts function immediately before wp_head();.

Is there a reason that we can't safely hook on to wp_head() instead with a high priority?

Both seem to work, but I like keeping my enequeue-ing in functions.php if possible.

Hi Mr Webb,

Including it in the functions.php is ideal if you know what you're doing. The documentation is geared towards beginners where the simplest solution is often the best. :)
