I have been fitting with Mitsubishi Diamana Golf Shafts since I started my fitting business. The Blue Board Archetype is the most copied shaft profile in the business. The soft mid profile delivers forgiveness to the often erratic tempo of many recreational golfers. the last three generations of the Diamana have changed very little. The Diamana BB is a significant change.
This chart compares the torque of the last four generations of the Diamana Blue golf shafts. Mitsubishi tells us high modulus 46 ton fiber was used in the bias plies and 80 ton fiber is used in the butt section of the Diamana BB. It is evident that torque, as claimed, has been reduced. The torque of the BB is 0.4 degrees lower than earlier models.

TPT Nitro Driver Shaft Review

I have a long history with TPT. i visited their headquarters in 2018 when they first entered the golf shaft business. My first review of the TPT Driver shafts was published in 2018. There was a restructuring of management and I lost touch until earlier this year. The USA distributor is J&S Golf. Their re-emergence into the USA market comes with a tour win by Jason Day at the AT&T Byron Nelson in 2023 playing the Nitro 15 Lo in his driver. Club fitters interested in carrying TPT shafts can send an email to info@TPTgolfshaftsusa.com.
The TPT Nitro new driver shaft comes in two models, Hi and Lo and I measured all versions of both models.

The TPT Red Fairway is not a new shaft, it was introduced in 2020. I discussed TPT’s manufacturing process in the review of the TPT Red Driver shafts many years ago. This short review covers measurement of shafts sent to me by TPT engineering to be included in my database.

MCA Tensei 1K Pro Blue Driver Shaft Review
Mitsubishi Tensei 1K Pro Blue Golf Shaft Review

The Mitsubishi Tensei 1K Pro Blue joins the Tensei 1K Pro White and the Tensei 1K Pro Orange reviewed earlier. The 1K carbon fiber replaces the CK, Carbon Kevlar woven material used in the earlier CK Pro version of this shaft. It is reported to be lighter and more consistent. Like the earlier CK weave the 1K weave significantly reduces hoop deformation of the shaft where the wall thickness is thin and is easily deformed.
Mitsubishi, unlike other shaft companies is vertically integrated. They make their own resin and carbon fiber which is combined into prepreg, the material that makes up the walls of golf shafts. They were first with high density prepreg, reducing the resin content by using high strength thin fiber. And despite the claims of other shaft companies to have the most shafts in play on tour, MCA’s 595 Win Count (as of this writing) is hundreds ahead of the nearest competitor. MCA has held that lead for as long as i have been fitting. The CK weave and now the 1K weave are the only weaves I have seen that significantly reduce hoop deformation just below the grip of a driver shaft. And that translates into overall tighter dispersion.

the Graphite Design Tour AD IZ Hybrid Shaft is not new release. It was recently pointed out to me that it was not in the database. Like most Graphite Design models, they do not get recycled with new graphics every few years. The IZ driver shaft has been with us since 2017. It is an update of the Graphite Design Tour AD DI with new materials. The Graphite Design IZ Driver and IZ Hybrid profiles are very similar. If the IZ or DI driver are your fit, you should be testing the IZ Hybrid in your hybrid or rescue clubs.
