I also own a bottle of Floris Sandalwood (sadly, no longer in production), and agree with you about the subtle scent and longevity. Another favorite of mine, similar in being a "close-in" scent with all-day longevity, is Jo Malone Black Vetyver Cafe -- I own, use, and recommend it (yeah, I know: the Basenotes review are "meh", but I'm just sharing my experience with it, and no one else's. YMMV... their's does).
