It can be strong, but it shouldn't be overpowering as long as you use them in moderation
Fresh and citrus is Himalaya by Creed. It once prompted a female friend to grab me as I walked by, smell me, and exclaim, "Oh, it's you who smells so good." Get a tester from www.scentedmonkey.com for the best price. Decants and samples area available on ebay, and Creed scents are carried in Saks Fifth Ave, Nieman Marcus, and a few other high-end stores if you want to try them first.
Mixing scents inevitably ends with the impression that you are trying to declare some sort of cologne jihad.
Recognizing a great scent (if you haven't noticed, I think that Creed makes some of the world's best colognes,) wearing respectable fragrances (not stuff you'll find at Wal*Mart, not Gio, not the typical stuff,) and knowing what you're talking about. www.basenotes.net has info on just about every fragrance ever made, and if you read up on what people say, what notes are present invarious fragrances, and generally have a decent understanding of the subject, you'll make a good impression. Knowing what's appropriate for when is also key; I'm not going to be impressed if you show up wearing Bois du Portugal for beer and pizza, and if you're wearing Acqua di Gio I'll roll my eyes like I do at the other ~50% of the male population who wears it because they heard it's good and think women will be drawn to them because of it. It's like calling tech support and lettin gthem know that you already checked that everything was plugged in and tried a couple of cables before calling to bother them; they know that you're not an idiot and will have some respect for the fact that you're actually educated and making effort.
Try something like DKNY Be Delicious for Men, which is sweet and a bit woody. Eau Parfumée au Thé Verte by Bulgari is a green, earthy scent. Overall, as an outdoorsy type, you'll probably look for a woody scent, probably with some patchoulli, rather than citrus or aquatic. I'll give you a couple more to try one I'm out of my exam tonight.
I absolutely love L'Anarchiste, I usually wear it for two weeks followed by a week of John Varvatos just to chang ethings up, but until a few months ago it was my only daily scent.
Everyone is worried about looking good, I don't know why more people aren't obsessed with smelling good.
