those are all really good questions...i have not tried all of the creeds/Aqua di parma you mentioned, so cant make comments on those...
Q) How about Serge Lutens what are the citrus / woody scents?
A)looking at your condition tht you dont like spices and leather, i suggest you stay away from Sl.....Citrus woody scents could scents like Paco - XS, Dior Dune, Dior Eau Sauvage concentree, lalique ph Lion et al.
Q) Also, if I am hitting the night scene in the clubs, what cologne should I use in my present collection or ( Creed, Surge Lutens and Acqua Di Parma) -
A) all are good for partying imho....my recommendations would be ST Dupont Noir, Dior Addict, Azzaro onyx/silver black - those 3 are pretty strong with excellent staying power and fits the club scene perfectly.
Q) Lastly, Romantic Setting - dinners or after work drinks -
A)Kenneth cole -reaction, Sean John Unforgivable OR "Paco - XS, Dior Dune, Dior Eau Sauvage concentree, lalique ph Lion"
