IG is really better for younger guys, to help give them a vibe of maturity and capability. A314 would be much better for you, because it is more versatile. It can be worn alone for work situations, and also softened with a social such as Instant Shine or Instant Honesty for social situations.
Just read through the mens section for ideas and mixes and such. You can also ask questions and get advice there as well.
You can wear Ammo with Instant Shine, and also with A314, or in any combination you choose. However, before combining them you do need to familiarize yourself with each one separately first. This post should help How to find your sweet spot… .
LOL, that’s pretty good! Though you probably don’t want to bother with A314 + Instant Gentleman (if thats what you were referring to), since IG is basically a lighter friendlier version of A314. They wouldn’t cancel each other out.
