Thx for the pos feedback, Slick.

My tractor delivers a max implement flow rate of 8.3 GPM. I figured that
I needed a minimum flow rate for my valve of 4-5GPM. That is based on
the fact that I am rarely running at full engine speed and the valve is in
parallel with the curl cylinder so flow is shared. A dedicated AUX valve
should be sized to the tractor's max output or greater, generally. In my
case, small size was very desirable.

What tractor are you going to be using?
