Well - a Black, Blue, Red, Purple solid hammer urethane ball, or any solid, or dull, or sanded urethane ball will hook early on dry heads, but that's why they created pearl urethanes (and LOFT is even better).
I have a Columbia Gold Dot pearl urethane with the standard 3-piece core that is just a straight as any standard plastic spare ball. At Reno it measured 81 hardness. Probably more durable than plastic. It hits pretty darn hard too! It hits so good that I no longer carry my trusty black hammer around. It's great for playing up the boards on a house shot on those days you want to practice that shot. It's predictable on just about any condition - no surprises. Pearl urethane 3-piece balls are great dual purpose balls.
