If you get the "bazooka screen", it will totally clog with pellet hops, but works great for leaf hops. If you skip the screen, and just go with a diptube pellet hops won't clog it. (But leaf hops will!
When I use a bazooka screen, I bag the pellets. When I don't use the bazooka, I bag the leaf hops. I hope that's not confusing! It makes sense to me in an 'I drink but I'm going to explain something mechanical' sort of way.
