YSL Rive Gauche pour Homme
Gucci pour Homme II (would probably have gone for Bulgari pour Homme, but it reacts really badly on me)
covers for office, casual, formal and date wear (in fact most of the scents can be used for 2 or more of those situations)
covers all the seasons
most of the scents are fairly idiot proof (except perhaps over applying M7)
I was tempted to add some niche scents, but the designer ones are much more foolproof, so I guess I didn't take advantage of the 'money is no object', and I'll get derided for being too mainstream, but whatever.
