I played the Callaway X20 Tours from roughly 2011 through 2018. Had them reshafted from PX 5.0 Rifle Flighted (~115 grams) to NS Pro 8950GH R-flex (about 100 grams). But, I ended up with a tendency toward toe hits - turned out the fitter didn't give me + 1/4" extra length on new shafts.
The solution: I started lining up my shots on the second quadrant of the clubface, rather than dead center.
This turned into more center strikes.In you case, check out shaft length as one factor in your ball flight. Also, a lower VCOG would improve the lift you get from the clubface. A CB type head might be what you need, as others have suggested.
Overall, the MPF is a good starting point when evaluating new clubs, or considering new ones. There can be exceptions, however.
Circa 2015, Ben Hogan golf clubs came back into production, with much commotion over the idea that they would make irons in one-degree loft increments from 22* to 46* - you could select the loft mix you wanted. Fitters told me that the PTx irons - a more forgiving offering than the Ft. Worth 15 blades - were the irons I needed. But, I didn't get very good launch despite trying a couple of different shafts. Two years later on a cold January day I came across some used PTx sets in a local golf shop. One stiff, the other regular flex. I tried both, and had the same problems from my original encounter.
Fast forward to 2018, when I got some quality time with grumpy's Ping brand at an outdoor demo day. The liked the looks of the new i210 model. Hot List rated it as Player's iron with a helpful cavity back, and Maltby gave is rather stern MPF = 338, in the Classic category (hard to hit) due to higher VCOG. Clearly too much club for my game at the time.
BUT, I located i210 demos with the AWT 2.0 R-flex (about 97 grams), and somehow started hitting really decent shots. The shocker: I hit several 4i shots off the deck 😁 that had pretty good trajectory and distance. But, I decided instead to get TE Exotics CB Pro Tungstens which were going out of production and had been cut to half price at a local shop. (Note: the Tungstens had shafts about 1/4" longer than my X20 Tours that needed the "2nd quadrant lineup" to get center strikes.)
So, the MPF system gets generally good marks for helping one sort through potential irons to try out. But, until you actually hit the new model, you can't tell for show how the ball will fly.
