Mizuno is introducing new technology with their JPX One fairway woods and drivers. The new tech for golf but used tech for Mizuno since it is found in their baseball side of the business, is Nanoalloy. Nanoalloy is a microscopic polymer layer put on the face of their titanium driver. What this layer does is change the elasticity of the driver face and increases ball speed over a larger area of the clubface. Adding a bit more elasticity with this layer, they are conserving the golf balls energy from the impact. 

Due to USGA rules, this technology falls under their coating regulations. Which add a correction factor to the ball speed testing done for conforming golf clubs. This rule was introduced when Taylormade went to their carbon clubface. Which I didn't know existed. 

I am sure that center strikes are at the USGA limits like all other drivers. This has my interest. I am always, "window shopping", for new golf equipment 😉

I caught a video on this driver; the face tech seems crazy. Looking at the heat map for ball speed, hitting it basically anywhere on the face only loses a few percent ball speed.

The surprising and counter intuitive part to me was that for flat faced clubs, ball speed loss is directly proportional to distance loss. For clubs with bulge and roll this is apparently not true.

The surprising part of that story being that the max distance potential looks to be a tiny pee sized area for this driver, and I feel in general for drivers.

The counter intuitive part being (the myth?) that blade irons have a pee sized sweet spot and missing that tiny spot causes dramatic losses. And that modern drivers, maybe 2017 on, have massive sweet spots and are ultra forgiving. Where in reality, if this heat map data is valid and reliable, it might be a bit of the opposite.

This insane tech driver appears to have a pea sized "sweet spot" while Mizuno Pro 241 irons are 28% more forgiving compared to the average of all clubs measured. Not compared to other players irons, compared to all clubs from all categories, players to SGI! The Pro 241 being essentially just a solid chunk of metal with no "tech" at all.

Which for me devolves into a whole mess of what is forgiveness really? And in measurable and quantifiable results how many yards, or feet, does that translate into?

Original definition use to or still is how far offline you hit it.

It might be better to think of it as consistency in retaining favorable launch conditions to optimize distance.

That heat map showed a gigantic 0-3% loss in ball speed. That is absurd. The true 100% sweet spot is tiny for all clubs. Good luck telling the difference if the sweet spot is under 3% in a sizable area.

Especially considering variation in launch angle, spin, and outdoor weather.

I think you're saying it's preposterous to think that the areas on this club are anything like what's shown here:

30mm toward the toe or heel loses only 5% distance? Highly, highly doubtful.

So a guy who hits the ball there and normally hits the ball about 250… will hit it instead about 238. By missing the sweet spot by about 1.2 inches? Highly, highly doubtful.

Heck, the high heel barely gets into the red, and orange is only "up to" 10%!

@M2R, I've never heard of "Ask Golf Nut" but I'm dubious of his claims in the video and really, really dubious of what's on his site: "Why AskGolfNut Is the Most Trusted Data-Driven Golf Resource".

Hmmmmmm.
