fraternities for a northerner

I will be coming to Alabama in the fall of 2014 semester. I am pretty excited to start a new chapter, because I will be a transfer student and a sophomore. I am interested in rushing a fraternity, I just do not know which one. Being from the North, and Philly raised, what are the best fraternities to look at? I went to a Virginia school previously, and got an idea of what greek life is. I am looking for a group of men who are classy, a true brotherhood, and just have a great time. I am a lacrosse player, and am pretty athletic if that means anything. So my main questions are, which fraternities should I look at being from the North and which ones to not bother wasting my time? I am pretty outgoing, so getting to meet people will not be a problem for me. Thanks in advance.
