Far more important to have enough supply then pressure.
Run 3/4" supplys as close as possible to the valve and you will have all pressure you want.
Picture this, buy a 3/4" garden hose, now stand on the hose and turn it on.
Pressure will still be the same on the incoming side but lower flow on the out coming side.
