Why can't all manufacturers list durometer rating?
on: November 11, 2017, 08:30:18 PM
There are things I don't like about Storm but I give them props for listing durometer ratings on nearly all their balls.  Through hook and crook found the ratings for all my non Storm balls except for my Venom Shock, my More Cash, Lane 1 Stealth Bomber and my Burgundy Hammer remake.  I can tell you that Burgundy Hammer is soft as hell and probably pushing the legal limit.

I think most companies stopped listing the durometer bit because virtually all of them are in that 73-75 range these days.

There are some 76s and 77s and my BVP Rampage (as well as epoxy ball) goes up to 78 but yeah I suppose you are right.  Not as critical as it was in the urethane days.

Because the only people asking about durometer readings are the same people that walk into a pro shop and ask for "1/2 side, 1/2 finger and an ounce of top weight" when getting their ball drilled.

For reactives I agree but only reason got interested in durometer in first place was due to my urethane collection where there its more important.  Gives you a good idea what ball works on what condition.  With chemical friction like with reactives less important (though based on values I do have I see a somewhat of a relationship between the softer the ball the more the oiler it is).

I doubt even they would care about durometer readings. Even before resin you virtually never heard anyone wanting to know what durometer reading of balls were (except maybe at a pba or nationals tournament check in ).

About the only time durometer readings came up at the bowling alley or proshop was when someone  wanted to know what a mill mark was for.

It's more for explanation.  Take the Match Ups and Tropicals for example, they have the same cover but the Match Ups hook significantly more and the core doesn't make up for that, but it's because there's a hardness difference.  Otherwise it's just not a big deal anymore like it used to be when people would soak balls in acetone or something.

If you think .035 vs. .009 isn't because of the core you're wrong.  2 points on the durometer didn't make a difference when durometer readings even made a difference. 

I wish I still had the test ball from Global that was a Tropical cover with a core with a differential of .120 to send to you to show you how much difference the core makes.

I was thinking of the wrong ball, yeah .009 to .035 is huge, I was thinking of the Ride core for some reason at .021, which is still a decent difference I suppose. 

Speaking of that, I had an absolute fit with the Rides specifically due to the diff difference between the 14-16 core and the 13 core.  Finally I had a ball for the seniors that didn't hook off the planet, and the ones that I drilled a 14-16 for were fine, but the 13s just hooked like crazy.  13lb diff was .045 though, instead of .021 like the rest.  Obviously I should have checked, but I just didn't expect it to be over double, and that was a stark enough example that I definitely learned a lesson there.  So you are indeed correct.

Yeah it was just me whining really.  The only time durometer might even be remotely interesting is for help deciding which urethane or plastic (pearl) ball you want to use for spares.

Durometer readings haven't really been important since polyester.  Urethane ushered in massive shell adjustments that far outweighed  surface hardness.
