Have used the Spider Venom on my Weber Performer and have been satisfied with the results. I recently purchased some Royal Oak Super Size charcoal, and used it (in a snake configuration) for the first time this morning to hot smoke some sausage. The Venom maintained 150℉ throughout the cook, but I noted a fine film on the sausage casing. After pulling the sausage, I noticed a rather large deposit of fine ash on EVERYTHING. The unburned section of the snake was totally covered in ash to the point it was totally gray. Has anyone noticed this? I've not had this issue with Kingsford charcoal.
