Well, he could do that, but, perhaps the information he seeks is this.
The reason I prefer the shape and size of kosher salt is that I try to build the backbone of all my ribs to be about the same particle size as medium grind black pepper (#16 screen). I do this as I feel the rub handles better and distributes over the meat better. Regular table salt is too fine, which can lead to uneven spots.
"perhaps...but then again...maybe not..."
careful there son, those ribs are boiling hot...
