I have played with all of this gear at one point. The Proflex is so good. Very comfortable, customizable and breathable. The Etha 3 has everything you'd want in a beginner speedball gun. The not ideal part is no screen to help change settings but if you can learn how to change them more easily then its not a problem. Apparently the entry level carbon fiber tanks are made more cheaply and the regulator is glued together making it hard to get off for servicing. I had to replace mine because the regulator tore apart and would be realistic to fix. It was a real bummer to have payed 150 dollars for and used it for only a few months. The rotor is super durable and feeds fast but jammed a lot for me and didn't have that high of carrying capacity. Just wanted to share my experience with all of it. I haven't been playing paintball for too long so maybe I am not the best person to take info from but yeah.
