If it's all about cosmetics, appearance, current fashion, proceed merrily. If it's about your hunting rifle...I would shape the cheekpiece in such a fashion that when you mount the rifle quickly, eyes shut, open your eyes...you will see a perfectly centered sight picture or crosshair without bobbing your head around like a chicken. Make the rifle fit the man rather than vice-versa.

Well this is a fine pickle we're in, should'a listened to Joe McCarthy and George Orwell I guess.
