Thanks for all the replies. I did actually talk to Dr.Diff and he suggested running the front right off the master and a adjustable prop valve on the rear. He said that if my front tires are real skinny that i may have a problem with them locking up. Not sure what size front I'm going to run but pro brackets (28x10.50x15) on the rear.
I guess I will just plumb in the adjustable prop valve and leave it wide open and turn it down if needed.
