Let's talk about urethane coverstocks and carrydown. Being on the younger side of this sight, I didn't grow up knowing what true carrydown was in terms of ball motion. I heard about it, but it was never something I had to consider. The last 5 years, I've become more competitive seeing all kinds of lane conditions. Something that has resurge for certain is urethane. The way some patterns shape, develop, etc have made it a viable option to many higher rev rate players (or in many cases a mirage that "ruins" the shot for themselves and/or others). In my earlier years of this kind of bowling environment, I thought urethane and plastic coverstocks created carrydown itself. From my understanding as of late, carrydown is created by balls that don't really flare. This can cover coverstocks of all sorts (including reactive). In opposite terms, this means urethane balls that do flare will NOT create carrydown. In a recent discussion with some PBA bowlers, there were some complaining about urethane destroying patterns and what not, one of them began to complain that a bowler did the same with a Black Widow Urethane. I haven't done any testing with the higher flaring urethanes, but this doesn't hold true with my philosophy. Personally, I think there's a chance that many of the newer oil patterns tighten up later in blocks regardless of lower flaring equipment. But I am not disregarding what happens when people do throws such equipment especially with a higher rev rate. Curious on what everyone will input here. This conversation was inspired by the Epoxy question since I'm sure many competitive two handers would love to have a ball with that coverstock.
