The Classic Pass is a move with a high degree of utility.
The pass is so versitile and I use it in alot of routines.
The original purpose of the pass is to reverse a cut. To use it as a control or color change is like using a shotgun to swat a fly. It works, but it isn't the best method.
It is true that you have a wave of younger magicians mostly that just show off their pass for the sake of performing the move(I myself have been guilty of this)
Yeah, that. I suspect that younger magicians practice the pass so much, they need to come up for uses for it.
To perfect it though, should I try to minimize the motion of the wrist? Was trying to reach a sort of Akira's pass but ofcourse im still practicing.
A couple of thoughts. First, if you insist on using the pass as a single card control, the replacement process (placing the card on top of a packet) is typically viewed as suspicious. I've seen people try to stick a card elsewhere (like in the middle of the lower packet) when that replacement process is used. Try to learn to do the pass having the card replaced into a spread. Another alternative is to dribble the cards and have the spectator say stop where they want to drop the card. This gives them more control and makes it less suspicious.
The cover for the pass should be a squaring motion. Try covering it with the right hand squaring the cards and the left hand stable. That would eliminate the "shake." If you can in the process of squaring the deck turn your body from right to left, the squaring motion and the motion of your body will provide sufficient cover. As Tamaritz says, the bigger motion covers the smaller motions.
Finally, practice while talking to your audience. This goes for the pass and any other sleight. Most magicians don't realize that talking is the best cover for a sleight.
