I purchased a Rival a few months ago to replace my Black Widow in my bag. My lineup was Raw Hammer Anger, Rival, and Black Widow Pearl. I got rid of the Black Widow Pearl recently, as its backend reaction was way too strong for what I needed - dry lanes. I replaced it in my bag with a Wrath Dead Flush, and let me tell you, it has been wonderful. My average has jumped 5 pins in the last month, and have had no problems making adjustments on my house's THS. These balls complement each other very well. WTG Columbia!
