Good to know. I just got a 10 Igloo from Walmart and am getting everything together to convert. I was also thinking about the 11" FB from Midwest, but it is out of stock. Good to know that the 12" is not as "snug" as advertised. I guess I will order the 12", now waiting on some stainless goodies ordered from BrewHardware to com in. Looking forward to make the move from extract to all grain..
