I have read pretty much all the threads here involving what I hope to be my last mod to my CG duo w/SFB. I have tried the reverse charcoal tray deal and, while it does work OK, I don't think it's as efficient as it can be. Does anyone have a baffle/tuning plate mod plan that really worked well i.e. more even temps and greater fuel efficiency? I really would like to see a proven method that made a difference in your smoking projects. Thanks in advance for your help.
