I had good success with a stainless scrubbie (Chore boy?) under my dip tube. I've done 3 batches with no filter of any kind, just using pellet hops, whirlpooling until I reach pitching temps, then letting it sit for 20 minutes or so. Draining from about 2 inches in from the keg wall. Leaves about 1/2 gallon behind with the trub cone. Last batch had 5 oz. of pellets, not that it is a lot.
