papersmile, so far I have tested the following Atelier Colognes:
Vanille Insensee - pleasant vanilla. I didn't find it rubbery, but a bit boring. I prefer Eau des Missions (Le Couvent des Minimes) and it's a lot cheaper!
Orange Sanguine - fresh juicy bitter orange top notes. Goes to a skin scent fairly quickly. I can't distinguish the other notes (I'm still developing my Nose!), but they're very nice. I prefer Shay & Blue's Blood Oranges, which is juicy bitter orange mixed with aromatic leather and musk, and lasts all day.
Oud Saphir - I tried this a couple of times. The first time it had a strong smell of a hard leather ashtray full of fag-ends! The next time I avoided the first few minutes and got the addition of a timber yard full of untreated wood. Then it settled down to a sweeter skin scent. It is very masculine to my nose.
Gold Leather - again a very masculine scent. It is heavy on the rum, but not in a good way, and I could smell the eucalyptus, wood and leather. It is sweet with a pleasantish dry down, but this is definitely not one for me.
Trefle Pur - this has juicy bitter orange top notes, like Orange Sanguine, but It is joined by herby notes plus violet leaves (which I love) as well as well blended amounts of patchouli, moss and musk. I really enjoyed this one. Definitely my favourite so far!
Longevity on all of these was about 3 hrs, followed by a skin scent for a further couple of hours.
