The MPF might be a good one to try, but I have not done extensive testing to compare how it’s spin compares to other mid/high to high launch shafts. It is a firmer profile for for each flex designation, meaning the R is a firm R and the S is a firm S, etc.
As far as manufacturing characteristics in a shaft to produce “low spin”, that is difficult to describe. The loft of the club, to a lesser extent the cg location of the head, the attack angle at impact, and the ball have a whole lot more to do with the spin than any dynamics built into the shaft. That being said, most manufacturers will describe a shaft as producing a certain trajectory and spin. Generally speaking, a high launch shaft will usually have a profile that is more flexible in the mid section and/or tip section, or both. If I am trying to achieve what you describe, I lean towards designing the profile to be softer in the middle, but with some firmness in the tip with torsional stiffness that is not too high. The MPF DR shafts do kind of fall into that type of shaft. Still, too many other factors as I mentioned, that can effect the spin that are not related to the shaft profile. The ProLaunch GWX is another shaft we designed for Grafalloy and the 60 gram options kind of fall into this category as well. The Tour AD’s, if you notice, all have lower torque ratings but are designated as high trajectory shafts. Although the torsional stiffness is an indicator of rotational stiffness, it is also an indicator of the overall tip stiffness of shaft. In my opinion, that is why they state that the tip firmness produces “optimal spin and launch conditions”. Optimal launch and spin conditions ARE high launch and low spin if you are wanting distance, and the lower torsional stiffness helps with the stability which can enhance accuracy.
