Redjake - I love your post. I am someone who doesn't mind a sport flanker, but I love 31 Rue Cambon as well. I do not know anything by Jo Malone, but it sounds like you know what you like.
By sampling, do you mean you wore them? I've bought fragrances that I liked sampling in the store, but that eventually weren't my favorite after a few hours of wearing them.
You can order samples from a decant shop (2 ml is plenty) and test wearing fragrances to find your next one; if you ever need to purchase another one. I just order samples, but pass on ever buying a full bottle, unless it's Chanel.
