How about Roses Musk or Roses Elixir for the 2nd bottle of 50 ml you are thinking of getting ?
Re. the complimentary 20 mls- Patchouli Leaves is a never ending Patchouli festival . So knowing me, I would go for Ta'if Rose.
( Highness Rose is gorgeous rose and nothing else but really 'up' there in price if you're buying straight from Paris. )
