I'm 5'7, 185. I'm 18 inches from shoulder end to shoulder end. Would this be good for me? The operator II they have is smaller but I dont want to look like a dude with a tiny plate carrier. Budget is like $350 and looking for at least level 3+ protection. I figured I'll upgrade the plates to level 4 later on.
