Why do I use only 3? Well my always on the patio cookers are my weathered warrior 22" and 26". I'd like to see them fade more over the years and really get that nice patina I've seen on other WW kettles. I put fire to my Yachtsman once just to see the color change. I cooked on my first Statesman for a while until I put her into retirement. No, I still haven't cooked on The Chief yet.
Some may shame me, hate me, look down on those of us that have grills we wont cook on. I look at it like this, it makes me happier to look at my clean Yachtsman, Chief, or Caribbean than to see them getting dirty, filled with ash and grease dripping and getting hit by the elements. I had my WW 22 blown over 3 times this past winter in storms.
Keep what you want to keep, pass them onto your kids or siblings if you have them. At this point my collection is really close to complete. The last ones I really want are too rare to search for every day and I'll stick to my rule to not pay more that my set limit. That has kept me grounded in this whole mess of Weberitis.
Or, smoke a joint and see if your perspective changes!
