Hey all just had a question, I am looking to purchase one of these DVD's at this time. I have been trying to get more consistent with my shot making and I recognize that these systems help me with certain shots that I struggle with. Now I want to purchase both of these systems, however I am leaning towards 90/90 as it seems easier to understand. I have watched many CTE videos and I have no idea what is being talked about. Now this could be because I have never actually seen the CTE dvd's, just seems like tons of terminology and math to learn. Perhaps I am wrong? Anyone have experience with both these systems care to chime in? As I only now what I have researched and found online. Thanks in advance.
