Very OT meant for Hugh H - Roth or no-Roth

I have spent some quality time looking at Roth conversions. Wow, that gets complicated in a hurry. Bottom line is it's not at all clear that there are benefits for me. So much depends on assumptions and goals. You would need to do a complex probabilistic Monte Carlo analysis including tax policy changes, longevity, market returns, and more. Plus, your goals key. For me it comes down to wanting to leave my estate to charitable entities and some family members, doing so with as little tax liability for them as possible. I am doing something different from Roth, reinvesting RMD and other investment income into income-producing assets. 60% was put back this year, not spent. Amazing how fast that compounds into even more income.
