The classic force is popular for its impossibility. If the person tries to back track, they might think that riffling in order choose a card was suspicious. But even though things like psy forces or the classic force arent 100% accurate, when you correctly hit them, you’ll have a miracle with no explanation that if done correctly, might even fool experienced magicians.
The classic pass is one of the most versatile moves in card conjuring, the possiblities that you would have with a classic pass can’t be compared to any other move(except for the double lift maybe). But there are a few critical problems with this move that make most people shy away from it: It’s really hard to really master the move, and to execute it with 100% accuracy.
Also, this move is meant to be performed in real life ( and not on camera ) in an offbeat moment. Even if you’ve spent hundreds of hours on this move, you can’t make it truly invisible, or at least invisible enough to be done under fire. As you said yourself, there are some amazing invisible controls like the Allerton control which could be done even if people are buring your hands, and require much
less practice, but if you learn the psychology behind this move correctly, and put enough effort into it that it wouldn’t be too slow or too loud, it would be one of the best moves you can ever use in card magic.
