I agree with Roland. Most ECOH are not QR after you get past 14x14 or 16 x16 . The only problem I can see is balancing the ECOH and the ssp. The high gallons needed for the ecoh will cause your ssp to overflow like crazy. I can't tell you how many times this has been my remote area, while the traditional remote area 100' away requires 3-4 psi less.

Also not that some EC (aka 20 x 20) with a fast response link are not QR.
