Your chest shape will effect the pitch needs for you and the way you do the majority of shooting. A thin chested man who leans forward in his shooting stance will need more positive pitch (longer toe) whereas a heavy chested man who stands upright may need negative pitch ( shorter toe)
You can do a trial by loosening the recoil pad screws and inserting a small wedge under the top or bottom of the pad to simulate pitch changes and see what suits you body shape and shooting style.
