I hear a lot about how effecient poly is to install, so were going to try it on our next install but I have a couple questions. What kind of reel holder or other method have you found to be efficient when pulling this stuff? Secondly, the friction loss chart I have on this poly 80 psi product says 1" tops out at 12gpm at 4.45fps. Is this right? S Sure limits the amount of rotors running on a single zone doesnt it?
