What's your marginal tax rate then? (With the state rate included)
If you are in the 15% federal tax bracket, and expect your income to get up to 70k next year. You will be in the 25% federal tax bracket next year. With that said, I would keep the month in the traditional IRA this year. Next year, I would focus on increasing your 401k contributions to keep you out of the 25% tax bracket. When in the 15% tax bracket, that is when I contribute to my Roth IRA.
I also live in a high-state tax state (California)...
