SDIRA - Roth versus "Regular"?

[Jim Farrell]

I am squarely on the fence of whether I should convert my existing SDIRA to Roth, and would love some input from members.

A bit of background: a while back, I rolled over funds from a previous employer's 401(k) to an SDIRA.  I've seen advice on some of the forums that one should just "bite the tax bullet" sooner rather than later, and convert to Roth. The thinking being that even a smaller pot of money--if allowed to compound and grow over a number of years--would then result in tax-free withdrawals down the road.

The assumption one must make in doing this is that the income drawn on down the road--since it's tax-free--would be more than if I kept my funds in the existing "regular" IRA, let those investments compound, and pay taxes when I withdraw.

Looking forward to responses!
