Hi utahchris.
I had that realization about 5 years ago, and made the adjustment. It felt odd selling out en total certain stocks from both my traditional IRA and Roth accounts, and then buying them in the other account. But I did it, keeping some solid anchors in my Roth and then adding my anticipated fast growers and solid growth stocks. That included FB, which has grown over 300% since tucking it into my Roth. My other top fast growing Roth positions are SHOP and NVDA, both well up since I bought them and therefore tax free when I am ready to use that money in the real world. Hopefully, never. 
I kept big blocks of AAPL, SBUX, and AMZN in my Roth and they are solid medium positions. In my Roth, I also have a few smaller high growth positions that will hopefully grow into larger ones. I feel good knowing that my 3 largest positions, SHOP, NVDA and FB will grow without tax worries. And I feel safe having AAPL, SBUX and AMZN anchoring the account.
As for selling out in one account and buying in the other, don’t pay any attention to price as it’s a wash. My cost basis for the SBUX position in my traditional IRA was $3.54. When I sold it and bought equal shares in my Roth, my cost basis changed to 20something. It is ludicrous that selling those original shares irked me. But it did. An emotional thing, I guess. But I have come to realize over the years, that there is no room for emotion or loyalty in buying stocks. Just cold analysis and common sense. Hopefully, I can continue to keep the emotion out when making future buys and sells!
Best,
Vivienne
