I can only say good things about the 1/2 bag of these pellets I've burned so far. I'd say they are MUCH better than a shoulder pellet. I can't hold my hand 6" in front of the heat exchanger for more than 30 seconds!! They DO burn hot! Ash so far...hard to say for sure cuz I didn't empty the ash pan but doesn't seem to be too bad! No clinkers! No fines sticking to the sides of the bags...none seen at all so far! If you find them grab a few bags to try. Sadly, I doubt we'll see them here again but I'll report in to my TSC source 

After fishing one bag there are no 'fines' to speak of but I did have about 1/2 - 3/4 cup of 'particles' at the bottom of the bag. These bags also came from the bottom of a pallet. On bag 2 and I DO love the heat from these babies
