I normally use Polo Sport, seems to be a popular choice.
I also have a bunch of colognes that I got as a "sampler" gift. Nautica and Nautica Sport are pretty good. Obsession for Men smells good but not real manly, kinda cinnamony. Cool Water is good as well. I can't remember what else is in there right now.
Some of the girls I knew in college loved Hugo Boss.
