So there are now five irons in the Ping line-up. From sleekest to most forgiving we have i-Blade, i500/i210, G400, G700.
The i210 have 33˚ so that gives you one area where the two models differ.

But Ping say the i500 should still launch pretty high, and land steep enough to make them playable.
Ping i500 irons review: The results

After hitting a couple of shots with the i500 irons, I started to get a bit excited.
I loved the sound and feel and I could see with my own eyes that the ball flight was very strong.
Before even looking at the SkyTrak numbers, I could tell the i500 were working really well for me.

I could see that they were flying a good few yards further than the i210 which I was testing at the same time.
And as you can see from the launch monitor data below, it makes pretty good reading.
Some might say the spin is a little bit low but for someone who has struggled with a high and spinny ball flight, these numbers are music to my ears.

My normal carry with a 7-iron is 150 yards so to consistently get it carrying 160 yards makes me think I could take a club less when attacking a green.
With the on-course testing at Rudding Park I still found the ball was sticking on the greens so I have no concerns about them bounding through.
Ping i500 irons review: NCG verdict
So are the i500 the best Ping irons yet?

Well, everyone is looking for something different when it comes to their irons. What I like to see might be the opposite so what another player is looking for.
But the i500 are the best irons I have ever hit because they give me exactly what I’m looking for from a looks and a performance point of view.

I want an iron to look and feel sensational – the i500 definitely tick those boxes.
