I do appreciate your response and don't want to be one of those "get off my post "
kind of guys.
I understand what you are saying if tax rates are the same as they are later and I agree. That isn't the case unless congress surprises us and extends them. At the simplest case, I see conversions at 22 and 24%(this year) better than 25% -28% withdrawals later. I also see having minimal taxes when one of us switches to single rates as a big benefit relative to marginal rates although no way to quantify without knowing when that happens. Since my pension goes when I do, her SS taxable would also change to 50% vs 85% which wouldn't happen if she is pulling $$$ out of a tIRA to fully cover expenses.
Finally, the market being down gave me the opportunity to transfer more qty of stock within the same tax bracket this year is the benefit I see. That makes it less to convert later and reduces the time to complete full conversion
