The colognes you are eyeing, are quite safe. I love Rochas Man. I always recommend Jordan Legend along with it. They are very similar, but Legend is less floral.
My number one all season recommendation is Gucci Pour Homme II. After that, would probably be YSL L'homme. Both are extremely versatile, and could be worn anytime.
If you have a perfumania around you, they have buy one get one for $9.99. I believe Rochas Man and CK One Shock qualify for bogo.
