I've done spares a couple times but this is my 1st attempt at trimming St Louis style. So far all the ribs I've done have been the Smithfields from WalMart. They're OK but I wanted to try some good, fresh ribs from a butcher. I was in Winder, GA for work this week and noticed a local butcher named Bentleys All Natural Meats, googled them and they get great reviews. I wrote down the brand of meats they advertise but it's out in the truck at the moment. I'll add it later. This rack of spares is 4.70 lbs and was $2.99/lb so it was $14.05. I also bought some rub they carried called Char Crust and I got the Roasted Garlic Peppercorn variety. Here they are cut. It might take some practice, I think I got them a little short but they'll be alright. The membrane came off much easier than it has on the store bought ribs. I'm going to 3-2-1 them in the morning with hickory I think..
