Honest opinions are always welcome.
I agree with you, Alan, that
the biggest improvement is the 22" size. You can mod your current WSM 'til the cows come home, but you can't give it a bigger diameter. It's not rocket science, but it does suggest that Weber is taking its investment in this product line more seriously than in the past 25 years, and that's a good thing. Given that it sounds like they're also bringing the 27" kettle grill back, I hope they will keep the spotlight on charcoal products and improvements for a while.
Regarding the ProQ, I've not used one, so I cannot speak authoritatively about it. I have only seen the video from the Illinois BBQ Society that compared the WSM with the big ProQ. You cited the clips and door as positives...not sure I agree about the clips, and the door is very small. Hinging it is fine, but we'll see how it holds up over time with use. Weber now has a clever door design that keeps it attached to the cooker or it can be removed. It also has a large, plastic handle that can be operated without gloves. In terms of fit, it's my understanding that Weber will continue to work on improving this...we'll see.
The only ProQ accessory I see that is interesting is the meat hanger. Everything else I see on their site is available elsewhere. From a practical standpoint, I don't understand how you're supposed to place the hooked meat on the rod or remove the hooks from the rod. Does one person hold the lid up in mid-air while another person hangs the meat? Seems like the barrel smokers are better at this...set the lid aside and the rod is hanging across the top of the barrel.
Another point of comparison is the finish. We know how the Weber porcelain enamel coating holds up over time. We don't know how the ProQ painted finish will do. Time will tell. We also have a lot of experience with great Weber customer support.
Again, good discussion! Let's hope this is not the end of Weber's investment in smokers, but just the beginning. I wouldn't have believed that a few months ago, but now, who knows? We'll see.
Best,
Chris
