I've done 'St Louis' style ribs once. I don't like the way they're cut. Too much gristle and fat

come around here anyway.

That sounds more like a full spare rib.
They start with cutting off the "back ribs", then you have the "spare
rib" and if you cut that lip of cartilage off the other end it is a St
Louis Rib. (all bone)
