Mitsubishi Diamana TB Golf Shaft Review

Mitsubishi Diamana TB Series Driver Shaft Review

The venerable Diamana Blue Board is now in its 5th generation, The 2021 Diamana TB series. Rather the reading me talk about what is new, just watch this video from Mitsubishi Chemical. 

The Diamana Blue defines the most popular shaft archetype, a soft mid profile. This archetype is available from virtually every driver shaft company. Many brands produce exact copies and many other produce variations of the archetype. The EI profiles of the Diamana TB Series are not much different than the 4th generation BF series. What is noticeably different are manufacturing tolerances. Mitsubishi Chemical is vertically integrated. They make their own fiber, resin and prepreg. That gives them full control over design and manufacturing. The TB series is available in 21 versions from 40 to 80 grams and in flex designations from R2 to TX. I validated what they claim, there is very little variance in Butt diameter and balance through the matrix of shafts. That makes life easy for the fitting technician.

TrueTemper Elevate ETS Golf Shaft Review

TrueTemper ELEVATE ETS Iron Shaft Review

The TrueTemper ELEVATE ETS is available in both taper tip and parallel designs. the Elevate ETS 85 and 95 are .370 parallel tip designs. The Elevate ETS 115 is a constant weight taper tip DYNAMIC design offered in R, S and X flex.

Here is what TrueTemper tells us about the ELEVATE ETS.

If you are not familiar with what I refer to as a DYANAMIC design it is explained with this illustration. Dynamic design constant weight taper tip iron sets are a shaft design archetype almost exclusively produced by TrueTemper. The EI profiles change with flex designation. This is discussed in the review of the Dynamic Gold. In many other taper iron sets stiffness is a byproduct of weight, as weight increases, stiffness increases while the EI profiles remain the same. The TrueTemper Dynamic archetype holds weight nearly the same from flex to flex while changing the EI profile. The Elevate ETS R, weighting 115 grams has a longer tip section promoting a higher launch. The Elevate ETS S weighs 116 grams and has a shorter tip section promoting a mid launch. The Elevate ETS X weighs 117 grams and has the shortest tip section promoting the lowest launch of the group. As you look at this illustration you can see how the tip to first step length differences creates three different bend profiles.

This is a vital understanding if you are considering the ELEVATE ETS taper shafts. You have the ability to pick a launch propensity while holding weight constant. Now, lets look at how these three profiles compare in overall stiffness and chart the profiles of the parallel designs.
