Hey guys, Just wondering, can any of you tell me what the exact color name is for this large MP? Do any of you own it? It appears blue-grey to me but it is referred to as being denim colored in the description...which I believe is more of a light blue color and no grey whatsoever (ala Devil Wears Prada MJ bag). Also any preference between small vs. large MP in terms of practicality, heaviness, etc. Thanks so much for any input!
