Why does my squat clean suck?

Question: I am able to clean more from the hang than from the ground, both in the power clean and the full clean - is this unusual, and should I be doing something about it?

While I'm not sure if it's unusual, especially in the world of CrossFit, I would say it is not ideal. My first guess as to why it is more difficult- you're not starting in a good position in the full clean. Nearly universal starting position for a clean: "Bar over the balls of your feet --- hips as low as possible as long as your shoulders are slightly over the bar. (The bar doesn't have to be in contact with your body until it is at your knees.)" When getting comfortable in this starting position, you should address the bar instead of puling it in to you, this eliminates the most variables. If this position isn't perfect for your anatomy, tweak it, still make sure you do the exact same position, every time. 

My second guess as to the difficulty- you're jumping too early. If you jump with the bar at mid thigh instead of deep in your pockets it will be forward in the catch, and as a result more difficult to secure. Be patient. Also, make sure your starting position for a hang clean is exact each time so that the practice is transferring into your squat clean. 

Thirdly, it is not unusual that as a lifter your tend towards either pulling or squatting. Continue to perform the full lift, pulls and squats in balance so they all improve.
