Hello, I bought a 22.5 WSM and had very poor success with it last summer. I used it 3 times and was not able to get a sufficient burn time of more then 4 hours. I was using about 13lbs of briquette charcoal by Royal Oak and it just burned through it insanely fast. It was a very windy summer where I live last year and think that had a lot of contributing factors to it all. I am hoping to get to try it out once all of our snow is gone for another round to see how it holds up. Royal Oak charcoal for me is like $7 a bag. Kingsford where I live is more like $25. I'm just wondering if this is a massive step up in quality. The reason I get Royal oak is because all of the stores near me sell it and not kingsford. However i'm starting to think that taking the drive is going to be worth it in terms of a quality smoke time. I've used Royal Oak in an offset smoker no problem and typically just add charcoal as I go. I've been able to get 12 hour smokes out of 7 lbs no problem however the size of my off set is a fraction of the wsm.
