Well lets see, the RS-1 core has a high diff and is probaly the quickest revving core I've seen in a Roto ball lately. Everyone we've been drilling them for have commented on how hard and early revving this thing starts up in the midlane. Since urethane is designed for early hook and control why overkill reaction with an early and aggressive coverstock and a quick revving core in the first 20-30 feet? Pearl Urethane....maybe, but then you have the problem of a super aggressive core and a shell with not enough bite so it'd be too weak for the mediums, too high flaring for broken down conditions etc. It's like putting a Ferrari Engine in a '78 El Camino.
I think alot of times you and I have conflicting views on roto equipment and other equipment based on geographical issues. You're midwest, I'm far east coast/mid-northern atlantic. On this side of the country not much has changed lane condition wise since the mid 90s. There are still alot of bad/older surfaces and the modern oils just can't cover up the flaws in the many centers with poor surfaces and temperature problems. The only thing new is maybe a little more volume in the heads so the particles and pourous reactives don't tear up the condition so quick. It's something that most bowlers cannot understand unless you experience it. In the summertime in a center that doesn't keep the A/C around 68-72 degrees the east coast humidity seeps inside and can blow out a shot in as little as 15-20 minutes depending on how people play the lanes. Due to the humidity and lighter volumes of oil in the area early roll and early flare is a big overkill out here on most of the conditions. Since I've spent the majority of my short career(only 9yrs) bowling up and down the east coast and never getting as far west as St. Louis I can only give a view on what I see in our region and when I travel to tournaments, and collegiate tournaments and experience.
From an industry standpoint it doesn't seem like many of these ideas would go over or sell well. Yeah the post is all in fun and everything but most bowlers want what is not availible and it's not availible for a reason. Urethane days are over and there's not much use for it other than entry level equipment. The Pure Hammer, Track Magic, and Thunder Flash are excellent balls but too condition specific for the average bowler that just wants a new ball to use on the THS, and those are the people that make up the majority of sales.
