Well, this post is either going to flame me, or spark a nice discussion. Whichever, it is something I want to get off of my chest.
Does anyone remember when urethane was king, folks talking about "2 o'clock" pin positions, or the "4:30 drilling" or stuff like that?
I always wondered how the ball knew what to do with an absolute pin position; everyone's track and PAP were different, but I was made to believe that a 4:30 pin would be early and smooth.
My eyes never believed it, but the brain was sold.
RICO has been around for a bit now, since 2008 according to the article on bowlingknowledge.info. (check it out here: http://bowlingknowledge.info/index.php? ... &Itemid=47
If you fix the drill angle for a ball at 45*, you will, by definition, create a variable VAL angle from customer to customer. In addition, when dealing with a symmetric core, the initial drill angle is irrelevant, anyway. Another variable, not defined by the "layout guide" is the Pin to PAP distance.
This drilling setup is somewhat of a sham. It will be an early rolling layout for asymmetrical balls, but really, there is no magic "pin in the palm" layout without hard numbers (coordinates, VAL angle values, pin to pap distances, etc.)
Want an early rolling, smooth ball? Grab an asymmetric ball, draw a 45* angle. Decide how much forward roll you want (longer pin to pap distances), or if you want to retain tilt longer (shorter pin to pap distances, ie. 4" or less). Pay attention to the VAL angle-- make it 60 to 80*. There. A full recipe for an early rolling, smooth reaction for speed dominant or rev challenged players who need something to start up on longer or flatter patterns.
Let's quit talking about RICO like it's a one-size-fits-all layout, where all you need is a 45* drill angle, and the pin in the center of the palm.
I'd be willing to bet dollars to donuts that someone out there has had a ball laid out like that, and it was a dud, while his buddy's ball, laid out the same way, was a monster. Now you know why.
Thanks to JustinWi for putting up enough information for me to finally wrap my head around this.
Flame or discussion. Am I full of shist or what are your observations?
