I've seen here on forum (I don't remember which threat it was) that someone said something about knuckle cracking. Is it true that it can weaken your slight of hand performance? I crack my knuckles all the time and I want to stop but it's already a automatic thing for me, sometimes I don't even realize I've done it. I realized my pinky can't go far down, for example for some moves I need my pinky to go straight down but it starts to curl in insted. Another thing is that my ring and pinky can't move one without the other. I know I have to practice a lot for some moves and I will, but I would like to know if stoping cracking my knuckles would help in any way.
