Hey buddy, I was new (still am... in an educated way) 2 days ago. Few hours and 290 threads later, experience level has changed.

Here are my 2 bits:

-Each card has spending meet. Analyze those if and how will you meet those.
-Which card are you inclined to keep it in future? Regular use?
-Then your preference... hotels? airlines? URs? MRs?
-Do you plan to churn (if you don't know this; research a bit more)
-Your income, future credit/loan possibilities (car/home loans)...

Consider all this before you work on your list.
