I failed the first time I tried CSR to due to trying to cook them like a bone in type of meat.
I did find (and some here will probably find this blasphemous) that if you re-heat them in the microwave and add a little sauce even shoe leather can become somewhat edible.
That said, with the way pork and beef prices are going I'm less and less inclined to "try something new" as I'd much rather not screw up trying to cook a $30-$40 piece of meat.
