Thanks pb4uski, this is helpful.
I think I was looking at the iOrp recommendations from the wrong end of the equation. I'm from a 'never touch the principal' family so the idea of actually selling an income producing vehicle often just doesn't compute.
As far as tax efficiency, I think I"m better paying the dividend rate from my taxable account rather than drawing those dividends as income from my IRA. So far anyway.
Or, you could figure out how to get them into a Roth account and pay no taxes on them in the future.
