Hi,

I’ve been fit a few times recently into various drivers but the common denominator has always been the HZRDUS Black Gen 5 in xstiff or 6.5 flex in Project X talk. Driver swing speed cruises in the 110-112mph range once I’m warmed up. I noticed that the MPF rating for the new MPF Pro Series + DR in xstiff is basically the same, 5B1M vs 5C1M. How do they compare to each other? My typical miss is a strike off the heel, but my face control is pretty good so I don’t think the difference between the playability factor of the two would be of much concern. I’d much rather try a different shaft then spend $700+ on a new fitted driver.

Follow any question, can the old MPF Pro Series DR be tipped to get the same stiffness as the newer + version?

The HZRDUS Black Gen 5 in X flex is slightly stiffer in the mid section and tip section than the new MPF ProSeries+ X flex. Not much and their deflection data is almost identical, so overall the HZRDUS might just feel a little firmer, but the ball flight could be similar between the two. The older version of the MPF in S flex, even though it was a firm stiff, is still slightly softer tan the new version X. It has a 3.5″ parallel tip section length, so you cold trim a little from the tip to stiffen it up, but be aware of the parallel tip length and the bore depth. Up to 1″ would probably be OK.

Thanks for your reply, Britt!

Would the old MPF ProSeries have a similar profile to the new MPF ProSeries + with tipping beyond flex? Or were there other changes made in the profile for the redesign? I have a MPF ProSeries in my driving iron, I really like the feel of the shaft even if I can’t hit the driving iron very well. That’s more of a function of my ability and that driving irons are difficult clubs to hit no matter what.
