I did made a Classic American Pilsener today which used 5oz of hops. I was very patient with letting the trub settle out after whirlpooling and got some nicely clear wort. In order to get a better whirlpool I removed the chiller and let the pump go for a few more minutes.
The false bottom did a great job of keeping hops out of my fermenter, too, but this is approaching its limit before it plugs up. I made a Pliny the Elder clone last year with ~10oz of hops and the false bottom clogged up bad. Holes scraped for the wort to flow through would quickly plug up and i eventually gave up and poured the kettle into the fermenter.
