My 2 cents - I would rather you index the market as a whole vs a target date fund, they just seem to lag a bit behind. There should be a vanguard S&P in that bad boy.
I love Roth, but I’ve never been a fan of converting at 24% taxes over qualified contributions, but there’s some math out there that says you still should. I just prefer saving the taxes now, making traditional contributions, and praying the brackets are not horrible in 25 years. They’re both good choices and make peace that you’re saving, which is the most important thing - the answer to which way isn’t always black and white.
