Mitsubishi KuroKage XT Shaft Review

Mitsubishi KuroKage XT

The first version of this review was of a single shaft, others have arrived, prompting this update. There has been some buzz about the KuroKage XT. It quickly became popular on the PGA tour. Mitsubishi’s dealers have been snapping them up as soon as the shipments arrive.

TiNiThe KuroKage XT is another of the Mitsubishi shafts to incorporate highly elastic Titanium Nickel wire into the tip section of the shaft. The wire, shown here, is embedded into the prepreg and rolled into the tips section much like any other flag of prepreg would be.

In looking for a profile match, only Mitsubishi shafts were close. An interesting phenomena I never see. It hovers around the Diamana ‘ahina and the first generation Diamana white. The third generation Diamana White has moved on to a different design, which departs from the original profile. I see a variation on the ‘ahina. The flavor is there, the rough edges softened a bit, but if you were a fan of the original Diamana White Board or the second generation ‘ahina, you are going to like the KuroKage XT. The brittle hardness of the Diamana White and the ‘ahina have been softened by increasing the torque of the shafts. Yes, you heard that right, the overall GJ torque profile has been progressively increasing from the White to the ‘ahina and now to the KuroKage XT.

This video was shot at the 2015 PGA merchandise show. Meet Tsutomu Ibuki, the genius behind the Mitsubishi golf shafts. As we talk about this shaft late in the interview the feel of KuroKage XT design is discussed.

Matrix Driver Shaft Review – REIGH & TIE Fitting System

Matrix REIGH Driver Shaft &
Matrix White Tie, Red Tie, Black Tie Driver Fitting System

The Matrix REIGN shaft is distributed exclusively through Matrix authorized club fitters. It is an elegant looking shaft with a laser etched logo and serial number. It comes in four structures, MCG, MTX1, MTX2 and HDZ. The MGC is the light weight game improvement design, mid to high ball flight and spin for lower swing speeds. MTX1 is slightly counter weighted for heavier heads or longer builds, the flighting and spin are mid range. The MTX2 series is traditionally weighted, and has a stiffer mid and tip section. The HDZ is premium Matrix, employing Boron and Zylon materials for feel and launch control. It is a unique profile emerging in a number of brands. A rapid loss of stiffness high in the shaft with a long stiff tip.

The technical discussion, measurements and testing results are available only to registered readers

The review samples are a subset of the REIGN line. But they are part of a new approach to golf club shaft fitting. Matrix created a 38 shaft system for Matrix Shaft fitters. They provide the fitting shafts and a software package to guide the fitter through the process of using their products of optimize launch and spin. I discussed this system with Tom DeShill, Director of R&D at Matrix Shafts during the 2015 PGA Merchandise show.

MatrixFittingGridThis fitting system also uses the Matrix Black, Red and White Tie shafts review earlier. The fitter finds the best fit in the Matrix Ozik Red Tie, then based on the optimizations target, continues testing with the proper weight and flex selected from the different design profiles to move the launch and spin toward the target.

My kit arrived and is being fitted with Club Conex UniFit tips. It will head to the range for fitting and testing, stay tuned.
