1911, 8x8 is too small IMO. I have both square and round baskets and can't tell much difference in the burn but they are all 16-17 inches across. I see some brethren here use the small diameter like you described for a short burn cook. I would suggest going bigger in diameter and keep the heighth what you have. Why did you do only 8 x 8?
