Our randall is not a hop rocket, so I can not elaborate on that product, but we use the "traditional" water filter housing technique but with a second chamber after the hop infuser. This cuts down on foaming significantly. OTOH if you are only pouring a couple pints at a time it may waste a lot of beer.
Also if it is clogging you might have it packed too full. Don't pack them in there. Just fill it and leave them slightly loose. The beer will cause the hops to swell significantly. Also be sure you didn't get any hops "dust" on any seals or inside the "filter" housing.
Any pictures? The second chamber doesn't have anything in it? I like some of the presentation aspects of Randalls but hate the waste introduced by the insane amount of foaming that seems inevitable with this setup since you're filtering carbonated beer through a billion tiny nucleation sites.
i can take some pics but it is essentially just two water filter housing linked together, hops in the first nothing in the second. much less foaming on the serving end.
