Agreed it wouldn't make a huge difference regarding morphs. If you look at modern combat armour, the big, heavy stuff is pretty much unisex. It's the smaller, thinner and lighter stuff (like the Kevlar meant to be worn under shirts) that would be tailored differently in order to take sex into account. Yeah, a woman built like Dolly Parton or an escapee from a Wyrmmaster render would have a problem, but otherwise it shouldn't be an issue.
