It's seems like you're not completely clear on all the tax-sheltered savings options that exist. There are two different savings
methods: pre-tax ("Traditional") and post-tax ("Roth"). And then there are two different savings
locations: IRA and 401(k). The two sets can be combined to create four different account types. The one you seem to be unaware of is the Roth 401(k). Perhaps your 401(k) plan doesn't offer Roth contributions as an option, but it makes it confusing when you refer to simply a "401k" vs. a "Roth IRA", because people who have a Roth 401(k) don't know how to answer.
I have about 95% Roth right now because of changing jobs and rolling over.
Hmm, so are you also not familiar with the Traditional IRA? The way I interpret this statement (in the context of your other statements) is that you had Traditional 401(k) money, and when you changed jobs, you rolled the Traditional 401(k) into a Traditional IRA, and then
converted the Traditional IRA to a Roth IRA. Is that what happened? If so, hopefully you did those conversions when your income was low! Otherwise your desire for a 50/50 Roth/Traditional split might be costing you a bunch of money.
For the record, I'm in the camp who uses Roth space only when my Traditional space is maxed out. So I will end up with something like 85% of my tax-sheltered money in Traditional IRAs + 401(k)s, and 15% in Roth IRA at retirement. Ideally I'd have 100% in Traditional, since I have plenty of post-tax savings to cover 5 years of Roth pipeline priming, but the limits prevent that.
