I agree with Kim here.
We have independent valves on the skimmer, the main drains, and two for the three returns. It gives you a lot of play room to increase/decrease suction or flow return to exactly how you want it or need it.
We didn't specify it to our pool builder (we didn't know anything at the time) but time and again when I see or read others set up woes, I am so very thankful that our builder went the extra mile and used unions and individual valves, and made the pipes very neatly spaced and organized.
