Back to the original question. I think the answer is it all depends on design. The amount of profile taper your bows limb has makes a difference in how much taper you need in your lams. The amount of reflex your limb has makes a difference too. Bows that the limbs work mostly in the 1/3 closest to the riser will shake your teeth out but if your limbs don’t have enough preload at brace your bow will have hand shock as well. It’s all trial and error on how much taper you need and how important tapered lames are. In most if not all bows they’re fairly important to make a good shooting bow.
