Thanks guys. two cp-075's on their way....

Hello All, I'm looking to mod one of my air cannons from a ball valve to a sprinkler valve. I cant find a valve locally so I have to order one without seeing it in person. . All my ball valves are 3/4" so I'd like to use the 3/4" rainbird, but I am wondering if the flow is any better thru the 1" val...
