Amazing, thanks Dennis. Well, now that there's both, I'm torn on which one to get. But your logic for revising the design and making it smaller makes sense, so I'll probably go with that.
But I welcome other opinions as well, especially from people who use the half grate a lot. The one use case of the half grate that still makes sense to me is just leaving it installed with no lower grate, so I can do a decent sized indirect roast while having full access to the charcoal without moving the racks between cooks. Anyone do this?
