Maltby Playability Factor - which irons are easiest to hit


Recommended Posts

Our Sponsors

I read a lot of posts about which irons are the easiest to hit and I haven't seen any posts/responses referencing the Maltby Playability Factor (MPF).

More information about what it is: http://ralphmaltby.com/what-is-mpf/

 

I remember this being a trusted source back in 2013/2014, but I haven't seen anything about it recently.

Looks like the Maltby experts just published their 2016 ratings

and I'm curious to see what others think about it.

This is all new to me. One thing I did notice in the rating is that Maltby says the Ultra Game Improving category is becoming more popular with tournament pros. Really?

My Sun Mountain bag currently includes:   TWGTLogo2.png.06c802075f4d211691d88895b3f34b75.png 771CSI 5i - PW and TWGTLogo2.png.06c802075f4d211691d88895b3f34b75.png PFC Micro Tour-c 52°, 56°, 60 wedges

I think ultra game improvement irons have always been on the pro tours. A noteable playerswho come to mind are Rocco Mediate, who played Callaway X-series (x-14, x-16, etc.) irons for the longest time, before switching to PXG

There are others but It's probably just not covered very much.. I think people forget that Annika shot 59 with x-14 irons (not even the pro series)

I knew it existed, but never crossed my mind to actually reference it.  Looking a number doesn't mean much to me, I'd rather just demo them and see how they hit.

This made me curious so I looked up my irons (Ping i25). The MPF is actually higher for the S55 (iBlade isn't listed yet) than the i25s or the newer i-E1 (current i iron), say what!!??

If you sort the list by highest rating, 7 of the top 8 are Maltby irons. Seems like a black box rating system geared toward the manufacturer getting good marks on their own clubs.

I took a closer look at the ratings and on ralphmaltby website it says, "In short, the higher the Playability Factor value generated by the formula, the more playable and forgiving the particular design should be."

 

A higher rating doesn't necessarily mean a better club, it just means it's more forgiving. I wouldn't choose a club just because it is more forgiving than others because there's a lot more that goes into which irons go into my bag. For example, top line looks, sole interaction, shot-shaping abilities, feel at impact, etc. or could overrule how forgiving the club is. Maybe others feel the same way.

 

I don't know about the bias, but I thought the results were interesting. Attached it for others who want to check it out. Looks like it's dated 05/2016.

noted on your point about rating being about club forgiveness and not what is better. But even in this context it seems suspicious that their irons rate the highest in a point system that they determine. I do think the list is still fascinating--there are blades that rate more forgiving than CB's from the same manufacturer...

I check the Maltby system from time to time just out of curiosity. It does seem to have some holes in it though.

HAHAHAHAHA

 

I like Pings.  I currently play the i20 irons, but according to the MPF they are Conventional irons.  Maybe I should play something a little more forgiving.  Well, I could play the Game Improvement Ping S55, or S56, or S57, or S59.  Since I am really old, maybe I should play something with a lot of forgiveness like the Super Game Improvement Ping S58.  That will improve my game.  {end sarcasm}

Funny you mentioned Rocco. A bud of mine used to be on the Callaway Tour Van when Rocco was on staff and he told me at the time Rocco played bone stock off the shelf X-14s except for the grips. He never had the staff mess with them any. I do remember back in the day on the minis Rocco played a set of Eye 2s. Rocco in person is the same funny excitable guy as you see on TV.

A buddy of mine over on WRX has the MPF thing somehow stored on his computer. He is also a classic club player and collector like I am. He pointed out that one set of irons the he and I both own has the hardest MPF listed. The irons are 1962 Macgregor FC-4000s I also have a fully restored set of the 1959 version of those. I would 100% fully defer to the MPF on that deal because those irons will tell on you in a heartbeat if you mishit one. Absolutely NO forgiveness at all

Like anything else the chart represents a starting point. Different swings, different eyes, different ears may produce different results.

 

Many fitters/builders use it as a guide.
