Which type of cologne should I buy?

With the colognes you suggest I'm guessing you're in high school. Any of the ones you suggested would be fine, but why not try to be a little different. Pick up something that the women will love, but isn't worn by every guy in your school. Check out a href="http://www.thecolognereview.com/2010/11/polo-blue-by-ralph-lauren/" rel="nofollow"http://www.thecolognereview.com/2010/11/…/a or a href="http://www.thecolognereview.com/2010/11/voyage-by-nautica/" rel="nofollow"http://www.thecolognereview.com/2010/11/…/a . Both are great light scents, and good for your age group. They also aren't overly popular and over used.
