Experience with Costco prime chuck ribs

[beegmahn]

Any experiences with smoking Costco prime beef chuck ribs? They actually look like 123A beef plate ribs to me, but they’re labeled as chuck. Trying to decide whether I should smoke these vs picking up some 123A plate ribs, which would be Choice not Prime.

I would go for the Plate ribs every time if they had them in my area.
Bigger, longer and meatier... That's what she said... :p
Chucks are danged good but are second to Plates.
Now I'm not sure how much Choice is going to stand up to Prime, I'd have to inspect both's marbling.
But pretty sure I'd still take the Plates.

I cook these all the time - they're always available at Costco Business Center near me. I either smoke them or sous vide them to medium rare. Both ways are fantastic.

Those look great. Never had them, so I was watching to see what they are.

They do look great, thanks for sharing. Those pics also leave me a little confused ...this site describes the chuck rib bones as being more round and the plate bones more oval to flat shaped. The bones in those pics as well as the ones I’ve seen at Costco definitely look more like plate bones. https://aggiemeat.tamu.edu/comparing-123a-124-and-130-beef-ribs/
