I used to think I was hitting a draw at times, and the ball was still curving to the right! I still prefer to play a little fade, but I’ve had to recalibrate my visuals.
If you make the effort to address the moves that cause a slice, you can straighten out all your shots. It won’t happen overnight, but if you’re systematic about it, the process will work.
In 2013, I changed to left-hand low, or cross-handed. And it’s helped a lot. At the time, the reason I switched was just a lot of inconsistency with putting. I was either making a lot of putts, or I was missing a lot of putts.
