I'm not an expert of clear vanilla - I don't use it. But, Wilton's bottle says "Clear Vanilla Extract" and then in small letters below says "Artificial Flavoring" so that one is imitation. I'm not sure how real vanilla could be made clear. My guess is that if you are using clear vanilla then it is imitation. Salted vs. unsalted butter I think is a personal preference. Some people only use unsalted in their BC, some use only salted, and some use a combination. You'll just have to experiment and see which you like.
