Besides weight, how would the following Iron Shafts compare: UST DHI A Flex vs Aldila NV A Flex 55 gram?
Also wondering why the UST DHI A Flex is considered a “distance” shaft and the Aldila NV is considered “both”.

The NV 55 A flex profile is stiffer than the DHI A Flex, so it will play stiffer. The NV also has a stiffer torque (3.9 vs 5.9), which will also make it play and feel stiffer.
No idea why one is designated a “distance” and the other is both. I think all manufacturers will say that a 50ish gram version of a shaft will help with distance. The stiffer profile of the NV might yield more control for some, so saying it provides both improved distance (due to weight) and accuracy (overall stiffness) would be a reasonable claim.

The D,B,C are values determined in the MPF formula. You are correct in that that designation is influenced by the torsional stiffness and the weight. There are other factors and we look at the overall profile of the shaft as well. NV is a firmer shaft and generally speaking for any given category a firmer profile is more likely to fall into the “Both” designation.

Hi Britt,
my question was in regards to the iron shafts (dhi vs NV).
also, I thought that D/B/C designations in the shaft ratings were a value determined by one of Ralph’s formula. Thinking that weight/torque might have a impact on distance/accuracy?
