HI Dewetha, How did the flat cast iron griddle work out for you? Did it help with below 225 degree temps? I may look at this as a way to lower the low temp readings and work as a heat sink too. Where did you pick it up and for how much? Im still fighting getting the smoker to go below 225 without the burner going out, and this looks like it may be an answer by covering more of the burner area than a cast iron skillet does. The stack mod looks good too.
