Joe: I think those cheek pieces look best if they are not paralle to the bottom line of the butt stock. In fact, I like them to be cut so there is more wood at the back end, between the bottom line of the cheek piece and the stock, than at the front. In other words, there should appear to be some taper of that section below the cheek piece, wider at the back than at the front. Too, the cheek piece itself should be shaved at least flat, and concave is better. You will see examples on originals of every shape, but that's what I prefer, and try to emulate.
