All I buy is spares, more meat an a better price. Ya just gotta look at em, enough fat but not to much, look at the sides ta see ifin there be good meat over the bones.
Try some different brands cause it does make a difference. I prefer Smithfields round here. Never had any luck at all with Tyson's, tough, not alotta meat an high priced.
Farmland seems ta be decent round here to. Guess the point is, ta just try some different ones an find which ya like best.
I trim some, just the strip from across the top a the ribs an anythin that be real thin along the sides. Smoke them up fer treats er ta add inta beans.
Good luck.
