Here's what I think...
Cool Water...STOP USE
Drakkar Noir...STOP USE
Polo Ralph Lauren...OK
The OKs are either too weak or too strong. The GOODs are a 'good' balance, and have some unique attributes (Z-14 and Grey Flannel). The STOP USE have been overly proliferated, wait maybe 10 years to start rocking it again.
Overall, you have very generic, non-special and nothing-modern fragrances. Time to go early 90s Italian. Here is my recommendation:
Smaple all of the Versace Jeans line (Blue, Green, Black, Metal, Baby Blue) AND anything Versace produced before 2000.
Then check Jean Arthes (below the radar but very modern and inexpensive) for something different every now and then.
