I had my first W class today and the instructor told us to make sure to ice a cake with thin consistency icing but I thought it would need to be at least medium. Anyhow, my question to you is, in your youtube videos, what kind of consistency do you use?
I just watched her video again, never gets old! 
Not sure if you know but you can PM (private message) her if you have a question - just in case she misses your post.
Be careful with thin icing consistency, If your too thin it will make a mess.. I usually do my crumbcoat over a cold cake(something that in class might not happen unless you ice it at home), and the icing is medium to thin. If its breaking your cake too much and you have a strong cake, then it might still be too stiff.
Just keep this in mind. add water slowly until you get desired consistency.
First few tries are trial an error.
It will get easier the more you do it!.
