I love the versatility in this Onyx Vibe! If the lanes are dry, I can move right and it will never over hook. If I'm on heavy oiled lanes, I can move left and play straighter. The coverstock on this ball is still strong enough to allow it to cut through some oil and still finish with power on the backend. I have this one drilled 75 x 3.5 x 55, putting the pin right next to my ring finger. My first 3 games with it were 300, 256, 257 for an 813 series. Its definitely a ball I will have in my arsenal for a long time.
