I used PAYE the first year because you can use the income from the previous year (when you were a poor intern) to get low payments. Then pay extra - more of the money goes to principle and you have some flexibility in your cashflow. The key of course is being disciplined enough to actually make the extra payments.
The next year I used DRB to get a much lower rate. I have about 2.5 more years and I will be free of the student loans altogether.
