Last year I tried the Pellet Pig Shuffle on my Ton of AWF's that were 2"-3" long.
Didnt work and I looked like a Dumb-A$$ doing it. Wife got a chuckle out of it. So I broke as many as I could up and tried to take out the longest ones for pics to send back to AWF. Breaking them down will work in your advantage. Smaller pellets = more volume = more heat.
What brand are they? Taken me a few years to learn what I like and what the stove likes. But the shorter the better (in my book).
On a side note. Somersets are the shortest most consistent pellet around me. I just found a new contender. I met up with Forum member bigwalleye on Fri and we traded some Pellets. He had some Greene Golds (Greene Team). Very short like Somerset, dark like Presto-logs, but HOT... Very Hot. I have not got a true baseline on the temps yet. Im only running the Quad to test these. But the results so far are looking very good

This is the 14th brand I have tried/tested now and the only other one that has my full attention. I have heard pretty good things about GT's. Never knew they were around me.
