Mitsubishi Diamana RF Shaft Review

50 Words or Less

The Mitsubishi Diamana RF shaft is the highest launching shaft in the fourth generation Diamana family.  Very smooth, active feel.

Introduction

While the Redboard and its descendants have never enjoyed the internet love given to the blue and white Diamana shafts, it’s still an essential part of the line.  Whether used in a fairway wood to provide some extra lift or in a driver, Diamana’s red shafts have delivered consistent performance to those with smoother swings.  I recently tested the latest generation, the Diamana RF, to see if it carries on that tradition.

Looks

Regular readers know that I’ve never seen a Diamana shaft that I didn’t love aesthetically.  While matte finishes are trendy right now, the Diamana RF goes with a glossy red that transitions to silver near the tip.  The Diamana branding is classic, as is the flower band under the grip.  Cool without trying too hard, eye-catching without being over the top.  Perfect.

Feel

All Diamana shafts are known for smooth feel.  The Mitsubishi Diamana RF takes that smooth feel and adds more kick.

To me, the Diamana RF has a small, smooth kick in the butt section and a more pronounced kick near the tip.  In both cases, it’s not a dramatic hinge-and-release feel, rather a smooth, drawn out kick.

Interestingly, the EI chart on the MCA website shows that, among the Diamana family, the RF has the softest tip but the stiffest butt.  This is an excellent example of how feel can be subjective and why you shouldn’t pick equipment based on a single specification on a website.  While I have no doubt that Mitsubishi’s chart is accurate, the way this shaft feels in my hands is quite different.

Performance

As a low spin player living in a world where the majority of new shafts are billed as “spin killers,” I was excited to test the “mid-spin” Diamana RF.  I don’t mind hitting low spin drives, but, living in a place where the ball rarely rolls, I was curious to see if I could tack on a few extra yards of carry instead.

On my best swings, I could clearly see the benefits of a the slightly higher spin I got from the RF.  The ball had a different looking flight – it was as if gravity didn’t affect it the same way it does my normal drives – and it carried farther.

The downside for me was a loss in accuracy.  Let me be very clear: that’s not inherent to this shaft, it’s a fit issue.  My swing has more in common with a gorilla lunging at a golf ball than it does with Adam Scott’s syrupy tempo.  To combat my…aggressive…transition, I need less “kick” and lower torque.  Players with smoother transitions will love the way the RF explodes through the ball, doing the work for them.

The Diamana RF-Series shafts are available in 50, 60, 70, and 80 gram weight classes to cover everything from light weight driver setups to heavier fairway woods.  Regular flex is available in 50 and 60 grams.  Stiff and X-flex are available at every weight.  For the biggest hitters, a TX is available at 60, 70, and 80 grams.

Conclusion

For the smoother swinger who likes a more active feel, the Mitsubishi Chemical Diamana RF shaft is a great choice.  In addition to the softer feel, it provides a little extra lift through higher launch and spin.  Make sure to visit a qualified Diamana fitter to find the right weight and flex for your swing.
