2 pump 2dump

I need new dumps and while I was shopping, I saw a setup with 2 pumps 2 dumps. What are the benefits of that? Just no individual wheel operation?

Benefits? None really. All that would let you do is have front and back maneuverability. Plus with the lines Tee'd off you will have a ton of body roll due to the fluid transferring between the sides. Just by adding 2 more dumps to the setup you would have individual wheel control.

Yeah I was looking at the electromagnetic coils for the dumps.
