Opening does not matter that much, especially for players less than 1600. As long as you follow the opening principles and understand the general concept of an opening, you will do fine. Your time would be better spent on middlegames strategies, endgames and tactics instead of countless opening lines.
That is why I created only one opening DVD so far. And the reason why I chose the Colle-Zukertort is because it is versatile and you do not have to spend so much time studying the latest theories as in some other openings.
In this DVD, I did my best to show you the key ideas and plans behind the opening instead of the imposible to remember details.
