I've only tried the Curls Rock Amplifier. I was tempted to buy the leave-in but I didn't. I like the Amplifier. I thought it gave me good hold and definition. I have a pic in my album (curly journey 07) that shows my hair and CRA. This is the only product that I've tried from Curls Rock Line.

ps. If you get this, a little goes a long way. I have thick hair that is almost BSL and I use 2 to 2.5 pumps on soaking wet hair.
Lotsa 3c curls
