Ok. 200 is a pretty good amount to work with. Look into the flyye carriers they should have something you'll like. I guess I'll recommend the 6094.
For pouches, check out and the pouches are all real steel, so quality will be good.
If you go with a 6094, or something similar, you'll probably want a cummerbund insert (they will hold 3 mags, and take up no molle space) a triple shingle for the remaining mags, a gp pouch for miscellaneous stuff, and a hydration pouch. (more than 2L won't fit on a plate carrier in my experience).
