Depends on the day, and the anticipated workload. I regularly fly raw data in IMC, but I don't do it if I am tired/fatigued or if I am flying with a 200 hour cadet next to me.
I do my best to maintain basic flying skills, and I encourage my F/Os to do the same, but at the end of the day the F/O is flying on my license, and I will have to take responsibility for any track deviation or unstable approach. Flight data monitoring and a culture of blame and punishment within the airlines I have flown for, sets a limit for how much "training" you can do on the line. Merely protecting my license, job and income.
