Bridgestone's New Dimples (e12 Contact)

[iacas 10,322]

Have you seen these?

[Vinsk 2,014]

I can’t believe I’ve missed this. I’m always browsing golf gear and equipment. Interesting looking for sure.

[boogielicious 3,018]

Making those molds will be a PITA.

[woodzie264 476]

Will that help the ball know where it’s supposed to go? 
 

Very cool. I assume the claim is extra distance and straighter ball flight? 

[DaveP043 2,536]

These remind me of a ball from the 80s (I think).  The Wilson ProStaff had "truncated cone" dimples, with flat bottoms.  I thought they were hexagonal shaped, but a quick Google search indicates that was a different ball.  Still, there have been lots of dimple shapes over the years.  To answer the original question, I have yet to see Bridgestone's newest idea.

What model ball will have these dimples?

[saevel25 1,909]

I wonder how effective they will be.

The raised area allows for 38% more contact with the clubface at impact than traditional dimples, yielding a much more efficient transfer of energy and improved core activation. The result is faster ball speed and straight distance with every club in the bag.

the cutting-edge CONTACT Force dimple design

If "cutting edge" isn't good enough to define effective, we can fall back on availability in white, matte green, matte red, matte yellow (presumably not at the same time).

I'm not convinced of the accuracy of that statement. I'm not a materials specialist (though I did stay at a Best Western, once) but when I look at high speed images of the golf ball deforming on impact it appears to me as if the surface of the ball is pretty much smeared against the club face. I'm not sure how that dimple pattern could provide more surface area to contact the club surface. But, that said, I'd probably buy them anyway 'cause, hey! Why not?

Here's Titleist's ball test lab showing what looks to me like elastic deformation of the ball on impact:

I bet they considered “improved playability,” but figured that phrase was taken by club manufacturers.

That's a fake video. That's not at all what a golf ball does.

Bridgestone introduced the new dimple pattern in their E-12 series last year.
I'm guessing it will be used in all models this year.
I played a couple of them last year, my friend is a Rep gave me a sleeve.
He indicated it created more surface contact on the club face, which helps produce more spin, I believe?

How many of us really need more spin?  A few need more backspin, but almost nobody needs more sidespin.  I believe I'll pass.

If I remember right, the E12 has a compression rating of about 50 and the ProV1 about 90-100.  

Supposedly the E12 with the lower compression works better for the lower avg swing speeds.

I thought I saw that dimple pattern somewhere last year.

Time for my regularly scheduled announcement of facts:

• A firmer ball will basically always rebound with higher ball speed.
• What a softer ball can sometimes do is spin a bit more. For some golfers, this can keep the ball in the air a bit longer.

I'll stand by my earlier comments about the dimples and impact compression until I can find data that tells me differently.
