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.
