Having found most places sell the ribs that look like shiners, I try to find meaty looking ones with some fat that I trim. With that being said, I have had good luck with Costco (California) baby backs that are cryovacced and have had worse luck with local grocery stores to the point where I dont buy them. I believe the Costco ones are Swift brand which might be found elsewhere.
