I have a few questions about the amezen tube smokers. First off I'm using a GOSM 38 propane smoker. I am wondering if the propane burner is gonna rob to much oxygen from the tube to keep it lit? Plus are you guys still getting a smoke ring when you use the tube? I have not seen them in action in person but on some videos, the smoke generated seems a little less than I would hope for. Can I light it from both side and double the smoke? I know that would cut my smoke time in half but anything is better than having to add chunks to my pan every 30-40 minutes. Thanks for any help on this.
