So I made a big mistake last year and sold my Jim Bowie. I changed jobs and needed the money but now I am back at my old job and I found a sponsor to cover all costs for this year. I am going to pick up a new Jim Bowie and Daniel Boone on Tuesday. We will put these into the rotation with our akorn and fridge for competitions. When I had my previous ones I did a few mods. I plan on doing these again but wanted to see if there are a few others people are doing. The mods I did before was a BGE gasket around the lid. Mineral Wool board wrapped in foil on top of deflection plate. Foil Wrapped the side diffusers. This helped a lot with equal heat distribution. I have seen the downdraft mod and it looked interesting. is there a noticeable difference? Instead of paying the $75 I will probably just make my own if it is worth it.
