I love Curls Rock Amplifier. Because it evaporates I don't even really think of it as a regular silicone.
I've been modified CG for a while, so I've been using occasional cones. I've also tried experimenting a much as possible to see what my hair will and will not tolerate. Either I have no idea how to tell, or my hair is generally pretty agreeable. I've had some bad luck with silicone conditioners, but I'm trying a-cone again because I'm reading posts from so many people who are doing well with it.
