First, if your drop at the comb is 1.5", that's fairly high and modern. Drop at heel of 3" is a lot and old style. The two dimensions don't seem to go together, IMO. If you're shooting high now, your heads-up style may be more the problem than the drop at the comb. Suggest you start planting your cheek on the comb and see if your high shooting goes away. If you shoot with your cheek on the comb properly, pitch will only be important to minimize felt recoil, in the way the butt fits against your shoulder pocket. Pitch will not make your gun shoot high or low, if your cheek is set on the comb, the way most shooters do it.
