So I bought the Fav. MM last month and while I love the bag, the strap doesn't seem very durable to me. I bought the Mono strap and I'm not sure if I should go with the Vachetta one. I do want to add that I will be buying the new mono Pochette so I will be able use this strap with it too. So which strap will be better? I love the fact this is a no worry canvas strap. Also, I do have the option of taking out the shoulder thing on this. Thanks as always!
