Core Shapes?
« on: August 17, 2017, 05:15:37 PM »
Do core shapes matter? Do you think they make a difference? Not so much the number's but the shape of the core?
It seems to me or at least I got it in my head that they do despite the rg and diff numbers.
What say you?

Bowling ball have NOT become complex...the confusion created by marketing & advertising by the manufactures is the biggest culprit...
Bowling ball technology has not advanced since 1997...particle/pro-active covers...

It still very simple-surface dictates length, pin to pap dictate flare potential & bowler is the ultimate decider
Equipment is a tool or enhancer of the bowlers attributes

So do core shapes matter despite the RG and Diif numbers?

OK I have to be the guy that brings in the hyroad and timeless. Same cover stock, same finish, very close to the same core numbers. Drastically different reactions. The difference is the hyroad core vs dual drive core. How does the dual drive core create such a large back end reaction than the hyroad core?

Drastically different? How so?
Unless bowling balls are thrown the same amount of times under the same conditions, on a CATs to eliminate visual perception...I do not believe a statement such as drastically different can be made
Now against a SureLock due to cover maybe but...

Sure do hear a lot more good things about the Hy-Road compared to the Timeless.  Core cover stock synergy is very important and your example proves it but probably not in the way you meant.  Seems like it is easier for a core to somewhat screw up a good cover stock than accent its strengths.

Kind of off the topic, but can RG be looked at in tiers? For example the "early" category of 2.46-2.5, the "mid" category of 2.51-2.55, and the "late" category of 2.56+? To boil it down a bit is there really that much difference between 2.46 and 2.49?

I'm sure this could be done with differential too, but from my experience I think the differences in differential ranges are more obvious than the differences in RG ranges. Which is part of why differential would be ahead of RG I assume.

Shell is way more important, but I have noticed thatvcirevdhell matchups are very noticeable.  Best example for me is Marvel series.  I hated the original Marvel, but like many people the marvel pearl was a great piece for me

Because due to the shape of the core, you're creating much different numbers after drilling. The numbers after drilling is what matters. I am willing to bet anything that after drilling (with the same layout) the Timeless will create more overall diff and a higher intermediate diff (after drilling). This is why you see such a stronger response downlane from the Timeless.

Ahh thank you for the responses! Drastically different may have been a bit much, but your explanations made a lot of sense

Diff dictates flare potential which creates traction thus more important than RG
The Timeless is comparable to the Brunswick Quantum theory of multi densities covers...you have a core that is wrapped by a lighter materials surrounding it and then a cover material...core numbers stay more intact from weight to weight
Drilling numbers always change but too many believe it creates some magical reaction...
Add 80 grit and any ball will react

Funny, just shows the difference in styles.  I didn't like the Vivid either, but Lucid was s great long oil tournament ball for me.  Not unlike the AZO Area that had the same core.

I started this topic because I've been trying to find something high rg that wasn't made for dry and wasn't flippy. I like low rg stuff because it's easier to control for me it seems but I have problems getting them down lane once the shot breaks in on one of the houses I bowl at. I'm going on my third season at this place and have two balls I like a lot here, a Bad Intentions and a Roto Grip Venus. The BI is my heavy oilier and shot shaper and the Venus is for the dry.
Anyways over the years I've learned that I favor the big round cores more but they always seem to come low rg,not the Venus and I absolutely love that ball. High rg,round fat core... But yes I agree it's not the be all end all as other stuff works well on different patterns and lanes. Thanks to all that chimed in to share their knowledge as it's much appreciated.

Surface will always dictate length but you need to look at slower response covers...something like a Rhino or Turbo/R or Nitrous...even if your rev rate is high enough and the friction strong enough...you can used sanded polyester with a strong weight hole to close down your angles
It's all abt response to friction and angles matching up
