I'd use both.
can I ask why you chose Duke?
I picked Duke for a variety of reasons:
-I lived in Carolina for about 7 years, so I am slightly bias.
-I received the most money from Duke (out of the t14).
-I don't want to study in the city (Philly, NYC, or Chicago). I've never been a city kind of guy. But I do see the advantages in studying in the city.
-I enjoy college basketball a lot. My UG didn't really emphasize sports (d3), and it was lame. So, I wanted to go somewhere that did.
-Visited (UVA, Penn, NYU, CLS, Mich, N/W, and Duke), and enjoyed Duke the most.
-Duke places well around the country. So, I'm not too worried about my job prospects after school.
-Believe it or not, weather was important to me. I tried to figure out what makes me happy. And warm weather does.
-Coach K and the Cameron Crazies.
-They have a fantastic gym too. It was great playing ball there.
It came down to Uva and Duke for me. I hope that answers your question.
