Very interesting post... I just bought a ton of LeCrete pellets and they seem to burn good, with allot of heat and not much clean up. The glass stays crystal clear for at least 4-7 hours of burning. I didn't notice the pellet size in the test bags I bought. I now have a ton and notice that there are some big pellets in these bags. Some pellets are an inch to 2 inches long. So far I haven't had any issues (since Friday) but I was asking myself if these long pellets are going to cause an issue with the auger. This is a good read. I assumed the pellet size has allot to do with how your stove reacts. I also find this article interesting because I was going to go with the Oakies ( which are very small pellets) the dealer had me try the LeCretes because he said they are bigger pellets and therefor will last longer and put out more heat. The LeCretes put out a little more heat than the Oakies so I went with LeCretes... reading over this article maybe the smaller Oakies were the way to go. They were both the same money to buy.
