I'm getting better hop utilization with the screen than with hop bags. Next brew day (Sunday) I will measure the temp in the column and see where it's at. When I ordered mine, I ordered it larger so it would fit closer to the bottom of my kettle assuming boiling action and convection action would likely be greater. I recirculate into the filter and have not experienced the kettle level drop that Blatz did. I use pretty much only pellet hops, so I still get a lot of debris in the kettle, but every bit strained out at any point helps. I use a pump and really like not having to clamp off boiling hot hop bags on the side of the kettle to keep them being sucked against the kettle outlet too.
