"Linear" means that it basically stays the same, so some might argue that such frags lack "complexity." Many "power frags" of the 1980s had a lot of notes, but also had a "creamy" quality, which didn't allow for easy identification of all the notes. L'Instant has quite a bit of development over time, but I wouldn't consider any of the stages to be especially complex. Jaipur Homme doesn't strike me as especially complex but it's rather linear. For me, a "complex" frag is one that has more than a few dominant notes, and the notes are ones that usually aren't thought to "get along" very well. An example of this is Charles Jourdan The Parfum. The notes for that one are: basil, bamboo, mango, peach, iris, almond, amber, patchouli, sandalwood, coffee.
