I use a RF smoker and use all hickory wood without the bark . I get thin blue smoke which is a real thing . Were it looks as if there is no smoke coming out of the stack. I actually get a better sweeter flavor with the RF than my WSM . For the guys have white smoke pumping out of there rig . Sounds to me they have not mastered there rig .
