Yes we surely need some Dior Homme on 'steroids' because the current Dior Homme lacks that punch. Its a beautiful fragrance but lacks decent 'longevity' and doesn't give out enough sillage. The 'cologne' version as you mentioned has been indeed a letdown. Sometimes i wonder how these companies come out with their 2nd version and instead of improving on the 1st, they fiddle with it and make it worse.
Opium ph edp is a fantastic enhancement of opium edt and as i speak i am enjoying it since i just put it on as my Sot-night.
