I agree with your comparison with shooting thin shots with inside rather than outside. If I need to cut a ball paper thin I use plain ball or inside. Its much easier for the brain to interpret deflection going away from the object ball rather than toward it because you always have the object ball to measure with.
Mind you if I'm playing one pocket I'll use plain ball or outside so I make sure cue ball comes back up table.
Yes, I've started playing one pocket the last few months & have gotten away from TOI except for a few certain types of shots, but not really any of length as the firm hit is usually not conducive to the situation.
