Yoder performs all smoker testing exclusively using BBQr's Delight pellets. So far, that's all I've used because I ordered a half pallet with the smoker. I've been happy with the results. I haven't strayed from hickory, as it's my favorite. I'll split a pallet and try some some cherry on my next go around. Per their website, they blend the flavorwood with Oak for more consistent BTU output between wood types. The big box stores are now carrying pellets. I might try a cherry on my next smoke, just for comparison. As of now, nothing is broke that needs fixin', and what I use seems to be in a good price range.
