I got lucky early on in my training by being a part of my high school weightlifting team. Unfortunately our coach had no clue how to train the clean, but I still had plenty of time with a bar on my chest. Now when I do front squats I use the cross arm grip, but that's just because I broke my wrist in high school and have never been able to maintain a good clean grip since.
It's true that if you have the bar in the right place you can actually take your hands off the bar. I'm always very lightly touching the bar, if at all.
The REAL trick is putting the bar down when your done and not using a squat rack or bumper plates. I've mastered the technique of actually dropping the bar and catching it with my hands. That movement alone has probably given me half of my biceps development.
