It allows them to concentrate a higher density of metallic grains to really amplify the feel.

The JPX919 Tour is a touch more compact than it’s 900 predecessor but has a new stability frame which makes it more forgiving.
The MP-18 SC offers a touch more forgiveness than the MP-18 blade thanks to it’s split-cavity design.
So that’s the lowdown – but how did they perform? Find out the results of the testing and James’s verdict on the next page…
Mizuno JPX919 vs. MP-18: The results
So I’ve gathered some data on both irons after hitting a load of shots on the SkyTrak launch monitor.
And the results are very interesting.
Interesting in the fact there’s very little between them when it comes to the performance.

Maybe a touch more ball speed with the JPX919 but launch, spin, carry and total are all very similar.

My normal carry distance with a 7-iron would be 155 yards but we’ve got traditional lofts of 34˚ on each of these models.
So 7-irons in the JPX919 Tour and MP-18 SC are basically 8-irons when compared the the model of iron I would normally use.
That’s primarily why we see a carry of 145 and not 155.
Mizuno JPX919 vs. MP-18: NCG verdict
So, seeing as the performance of these irons are pretty much exactly the same – I wouldn’t say one is easier to use or more forgiving than the other – it’s all about looks.
It really comes back to the original question – are you a JPX or an MP player?

Are you all about the classic blade or are you a bit more ‘edgy’ and modern?

And that’s a question that only you yourself can answer.
Which model would I be leaning towards – if I was good enough to hit them consistently?
From a looks point of view, I’d be very much leaning towards the JPX919 Tour because, despite being in my mid 30s, I’m still down with the kids.
But after hitting both, I just seemed to enjoy using the MP-18 that little bit more – the look, sound and feel of them is simply sensational.
They’d excite me every time I went to play or practice with them.
So despite being young, athletic and aggressive just like Koepka, I’d be more than happy to settle in for a Netflix and chill night with the MP-18.
