Interesting - I originally started using a home made hop sock as well. Basically a 5G paint strainer bag strapped to a 6" PVC coupler suspended over the kettle. It worked great and was super cheap, but again, hop utilization becomes a factor. The hops did tend to bounce around in the bag, but I wonder if one of the items here would better encourage the hops to float around more increasing the hop utilization? Might be another alternative to helping me get better recirc through my CFC... Waterlogged I'd be interested to hear if you notice any difference...
