DF is 8774 btu, .1% ash, $365/ton. Gold is 8900 btu, .21 % ash! and $300/ton. Seems like a no brainier to go with the Gold. About the same heat and ash, but $65/ ton less. Am I missing something here, or is there more to consider. Who has burned both and can offer a first hand comparison. I have a Harman P68.
