There are clearly times where working the ball one direction or another makes sense, assuming you have some confidence and competence to hit it. I play a draw on almost all my shots and know that my mishits will either go short or farther left from the target which is helpful in disaster avoidance. The little time I attempt a fade is if there is a tree in my way and I want to get to the green (or close by) knowing that getting closer to the hole from a SG risk/reward sense. I also play a fade when I have a significant side hill lie with the ball below my feet albeit I’d be happy if the shot ended up going straight and I’m trying to be more fade-like in my swing path to avoid the heel digging into the hillside. I’m less likely these days to hit fade when there is a large cross-wind but I think that may be a legitimate strategy as well.
As a huge @Adamyounggolf fan, I think regardless of whether you take it out on the course, it’s worth practicing shaping to get a feel for it and to train your body to make micro-corrections when you swing. I’ve rapidly improved my strikes by doing shot shaping, purposefully hitting on the toe and heel, and all the tools in the differential toolbox and it’s helped a lot.
