I've played around with a couple. I think I got a couple 3" balls. It's amazing how much even pellet hops expand to fill the entire area of the tea ball even if it's under half full when you put it in. I haven't given up on the concept yet, but may try moving to a bigger one. I've also been thinking of using them for a second dry hop in the keg.
