the only pellets I use now are Kingsford Hickory, Bear Mountain Oak.
I still have some leftovers of others that I will use up by mixing a little in with the good ones.
If the package does not say EXACTLY what is in it, then they are hiding something!
100% Hickory is what Kingsford says, Pit Boss does not give any information on their newer labels, they mostly say blend but don't say what it is blended with. I stay away from those that hide their ingredients
