I was wondering what you think of this Maltby playability factor or MPF?

Is that something you would go after when buying new irons?

And also what do you think of Tom Wishon drivers compared to Nakashima Drivers?

Best regards from Iceland

I know that there are those who place value on the MPF, and those that don't.
I like it from a technical standpoint, but find it doesn't necessarily translate into a useable guide as the weighting in the system puts too much favour on offset and VCOG as playability factors.  As a fitter, offset is something to use to help directional control... but I digress.
As for TW vs Nak?  I suppose the question is, what do you need out of a driver and what do you like to look at?
They're both quality designs, but I'd say that Nak doesn't offer anything nearly as forgiving as the Wishon 919.

MPF is a guide and a little course rating system.  Generally if you have 2 clubheads you like, a higher MPF will generally give better score over time.

MPF is a formula where Maltby based on his experience has chosen which and how to weigh certain physical parameter of a club.  That placement of centre of gravity, size of face, perimeter weight, clubheand MOI, offset count in playability is out of the question.

I use the rating as a help to find suitable clubheads and then I look at each parameter.  Vertical centre of gravity for proper trajectory.  I think it is a very important factor since it also affects feel.  Personally I do not like offset that much...
Horizontal distance from hosel to centre of gravity combine blade length and perimeter/toe weight in a good manner, I think.  And it tells me if the designer have been able to put the COG in the middle of the face or not.  For lower lofted irons, this is important for solid hits and toe forgiveness.

For a better player hitting down, the VCOG should not be too low, but the horisontal centre of gravity and MOI can be as big as the player could accept playing with.  For a poor player hitting flat  and short and unsolid and picking the ball the VCOG can be as low as possible and the rest as easy as possible.

The system tells nothing almost of feel, something that is important.

I cannot see there is a better rating available so I will use it.

I like a lot of what Maltby does, but I pursue the physical reasons why clubs work. 

So I sort of use the system, but always look at the individual parameters.
