This is our first year with a pellet stove, a King Ashley 5500, so we have been trying different pellets to see what works best for us. We started with one ton of Lignetics. There were very little fines, no need to sift and very little, fine ash. We bought 2 tons of Barefoot which had almost no fines and very little ash also. The both work GREAT. We bought a 1/2 ton of The Hamer Hot Ones ULTRA Premium which have been an "ULTRA" HASSLE. With the first two brands we were able to dump the bags directly into our stove. We did this with the Hamers and ended up having to scoop the entire hopper out. The bag had so much fines there is no way we could leave it. We have had to sift every bag of the Hamers and get 6 cups/ bag of fines. We find this unacceptable. The Hamers due burn hotter than the other 2 brands, however you'll need it to warm back up after your outside sifting the bags. The difference in the amount of heat just isn't worth it to us. It will be Barefoot and Lignetics for us in the future.
