I've been looking forward to opening my 2ml decant of Decision, and today's the day. It opens with citrus and medium to sharp aromatic woods. It reminds me of being in a library, but it's nice. Rough edges smooth out after an hour, but library smell remains to the 1.5 hr mark, then mellows out. At 2 hrs, smooth medium-toned woods dominate the fragrance, with a touch of some warm spices. Vanilla is listed, but its very subtle; maybe more of a complimentary role? Sillage is moderate to strong in the 1st hr, moderate to mild to the 5 hr mark, and steady mild beyond 8 hrs. Very impressive! Most Amouage fragrances are first and foremost, INTERESTING, and this is no exception. Sharp wood can sometimes be sour and unpleasant, but this doesn't go that way. There is enough balance and depth to keep it smelling good and still unique all day. It's very stable, and doesn't change much, which is a good thing with this perfume. I like it so far, and I'm also looking forward to future wears. Keep smelling great brothers!
