(oddly enough, we used to have a copy editor who would change "prick" to "pierce" on every instance because it was coarse.)
I do not prick, except of course, to check internal temp with my thermapen. Of course, natural casing will quickly seal that off. I use cast iron, medium heat, bring to internal temp of 155. The cast iron will nicely caramelize a natural casing. If grilling, which I will not do with a rich and fatty sausage, medium and indirect.
Both Ruhlman and Rytek Kutas have led me to this method.
