MAC Studio Sculpt Review...Yes I'm Alive

So if any of you know me by now you know that I am not one for the more "natural" look. I reeeeeeaaaaaally like full coverage. I was told that the Studio Sculpt from MAC should really be me next purchase sooooo after a few jobs and was excited to add this to my collection. Not only did the girl at the counter swear that I was to get NW 30....I am NW 15 normally....but she applied it with the #190 brush which is infamous for streaking and she said that I would only need a pea sized amount...as she frantically tried to spread it all over my face. I decided to go with the NW 20 because of the season and said I would better see the results I was wanting applying it myself. I am still VeRy on the fence about this. Is the coverage is full...YES!!!! Do you only have to use a pea sized amount....kind of (if you use it with moisturizer). Would I recommend it...I would reeeeaaally like to wait until winter to see if I like it better then because ObViOuSlY it is summer and I sweat it all of anyway and then the consistancy is wierd. I like my foundation to be a bit more liquid than mud but it still gives great coverage. Any one else tried it???
