If your lowertaxes will come in retirement, then go with a Traditional IRA to get the tax break when your taxesare higher, and pay taxes on your contributions once you arein a lowerbracket.
Conversely, if you think you'll bein a lowerbracket, you should opt for the traditional IRA, taking a tax deduction at your high tax rate today while knowing you'll pull those dollars out of your IRA at a lowertax rate once you're retired.
Similarly I plan to create Roth ladders with my pre-tax retirement assets once I retire early and amin a lowertaxbracket (with income primarily being from rental properties).
