This is a little trickier than just putting a restrictor on the work port line....
First of all, a constant flow is a constant flow PERIOD!!....and what a RESTRICTOR will do is INCREASE the PRESSURE.....to make work port flow decrease, part of pump flow need to be DIVERTED.....PERIOD!!
If you do not "feather" or "fine meter" your control valve, the is pressure relief valve will have to be the "diverting gate".....
And if the pressure relief valve diverting, the pressure is already at max, and your two stage pump have "geared" down to low stage....
So if your are happy with a setup that converts 90% of power into heat and the rest into lifting the log......yea then you can use a restrictor on the work port line....
I would instead make an arrangement that limits the spool travel in the log lift valve....that way you cant, by accident, over speed the log lift...
My picture is used for another forum, float spool, but it still shows what I mean...
