Just finished testing two brands in my Accentra 52i. The FSU's produced good heat but also are the clinker king for the brands I have tested so far. FSU bags had some fines but frankly the 52i chews right through them so I really haven't seen the need to filter or sift them out. The IG's produced more heat and you could easily see that the room temp was maintained with far less flame activity than the FSU's. After the last of the IG's went through the stove, I shut it down and in cleaning I found absolutely no semblance of any clinkers. There were less fines per bag compared to FSU's and the ash produced was similar to the FSU's in quantity but was a little lighter and fluffier.
So far the winner of my unscientific testing is American Wood Products Ultra Wine Pine. Next up in the box are a few bags or TSC North American hardwood/softwood blend and TSC Big Heat, I believe a hardwood pellet.
