Mizuno to launch three new golf balls

According to Mizuno Golf’s European website, the company will launch three new golf balls in March 2015.
The new golf balls will include Mizuno’s MP-S and MP-X models, which are designed for better players, but most interesting is the company’s new JPX golf ball.
The JPX golf ball has Mizuno’s new “dimple clusters,” which are micro-dimples located around the larger dimples on the ball’s cover that are said to improve aerodynamics. The design was created by working closely with the Fukuoka Institute of Technology in Japan, the company said.
[quote_box_center]”The micro-dimples have little effect at higher ball speeds generated at impact,” said Masashi Tamakoshi, head of golf ball development for Mizuno. “However as the ball peaks and slows, they start to take effect. By stalling the descent phase just a fraction, we were able to increase the JPX’s overall airtime.” [/quote_box_center]
According to Mizuno, at least five Japanese Tour players will use the MP-X golf ball, and Chris Wood, a Mizuno Golf staff player on the European Tour, is also testing the the MP-X golf ball.
The balls are not expected to be available in North America.

Tour Edge shares photos of never-before-seen square driver from 2007

The year was 2007. The famous/infamous Nike Sasquatch Sumo2 was released the year prior, ditto the Callaway FT-i. It was a (brief) time when, if you were a driver, it was hip to be square.
Fast forward 16 years. Tour Edge revealed on social media this week that it had plans to add right angles to its Exotics line with an epic #TBT post, writing:
“For this #throwbackthursday we’re going to prove that sometimes a product just wasn’t destined to come out…
“That’s the case with this one-of-a-kind Exotics XSi square driver.
“The XSi stood for XTREME SUPER INERTIA, and we were following the design trend of the day back in good ol’ 2007…
“But [in] the end cooler heads prevailed and this one was left on the shelf.
“Literally, we just found it on a shelf in our “museum” and almost every single person who was here at the time had forgotten about it, or just plain never knew it existed.”
Check out photos of the Tour Edge Exotics XSi, below!

Not available in the US? Quite frankly My Dear – Who gives a Damn about the US?
And – Dear Fellow Gearheads – hadn’t you considered that the Rest of The World also logs into GOLF WRX, not just you guys? Take your heads out of your butts and concentrate on finding a way to win the Ryder Cup or perhaps you never will again. Just keep telling yourselves how good your (made for television) PGA Tour is! Heard the latest? Sponsors want 15 hole rounds and 3 day tournaments – makes better television, don’t you know?

Not available?? So what! You never lusted after something that was not available? Oh man, they’re over there with their balls in the air a fraction longer thanks to those dimples so unavailable to me! I want those dimples so bad I’ve already put a tour ball in my vise and with a 6 penny nail am pocking it with heretofore unseen dimple clusters. Now it’s non-conforming? Oh no! What’s a poor, unproperly dimpled westerner to do? Time to remember the rule: “Thou shalt not covet thy neighbors balls, nor his cup-faced irons, nor his fourteenth driver released by that company this year . . .” Believe me . . . in just about all our cases it’s NOT the ball!

I have used the older Cross Eight Mizuno balls occasionally, and those were really good, excellent performance/feel

You’ll be able to get them in the U.S. as long as you’re willing to pay a premium for them on ebay.

If the micro dimples help, why not have it on the higher end ball????

Wait ill next year when they launch their new ball which uses their hyper super micro tri-dimples technology. The design was created by working closely with the Fukuoka Institute of Technology in Japan, the company said.

Obviously didn’t read the article. They aren’t effective on higher ball speeds so they are pretty much redundant to better players. Hence part of the JPX brand rather than MP.

And you obviously mis-interpreted the the article… They have little effect at IMPACT, but take effect as the ball starts to slow down and descends.
“The micro-dimples have little effect at higher ball speeds generated at impact,” said Masashi Tamakoshi, head of golf ball development for Mizuno. “However as the ball peaks and slows, they start to take effect. By stalling the descent phase just a fraction, we were able to increase the JPX’s overall airtime.”
