Well I had 7 bags of OHP's left over from last year (the first year I got the burner) and I stacked this seasons Somersets on top of them. I have just got to the bottom of one column of somersets and reached the OHP's. I burned a bag yeasterday and I now have to put it on this list. I didn't know any better last year because I had not burned a good pellet. The OHP's are horrible compared to the Somersets. Orange flame, dusty, long pellets some over 2", little heat, very dirty pot after one bag and ash everywhere. No wonder I was cleaning my stove twice a day last year. I wouldn't use these unless it was the only thing left on the shelf in Mid January. I'll blend the remaing 6 bags off in the hopper with the Somersets.
