Mitsubishi Diamana RB Driver Shaft

Hi Erik,Absolutely! I'd be happy to help.Since you're already playing and enjoying the Diamana RB 53 Stiff in your driver, my recommendation would be to stay within the same Diamana RB family and simply move up in weight for your fairway woods. This will maintain the same smooth feel and shaft profile while providing the additional stability that fairway woods typically benefit from.My recommendation would be:7 Wood: Diamana RB 63 Stiff9 Wood: Diamana RB 73 Stiff (or 63 Stiff if you prefer to keep the overall club weight a little lighter)We can certainly build both shafts with the correct Cobra DS-Adapt X adapters and your choice of grip.One quick question: What is your approximate driver swing speed or your average 7-iron carry distance? That will help me confirm whether the 63/73 combination is ideal for your game.I look forward to hearing from you!Best regards,JimGrips4Less

Not exactly. And this is actually one of the more misunderstood shafts in the Diamana lineup.The RB is mid-plus launch with mid spin, and it has an active tip section. That profile is designed for smooth-tempo players who need help getting the ball up — but the key word is smooth. The RB rewards a patient, accelerating swing. If you're a fast swinger with an aggressive transition, you're not the right fit for the RB — and you'll likely see the ball go sideways before it goes high.For a fast swinger with a genuine low-launch problem, the better answer is usually the BB or the GT. Both sit lower than the RB in spin, and the BB in particular handles aggressive swings better than the RB does while still launching higher than the WB. The RB is more about adding carry through feel and tip activity than about giving a fast player more height. Fast swingers who overpower a soft tip tend to actually push it lower, not higher. So if your speed is there but your launch isn't, then start with BB or GT. If your launch problem is more about not generating enough speed or carry in the first place, then yes, the RB is worth a look, especially in a lighter weight class.

Yes, and here's the key thing to understand.When you're hitting off the deck, you have to generate your own launch — the ground is in the way, the swing arc is tighter, and there's no tee to help. A shaft with an active tip section actually works with that dynamic by helping load and create upward force through impact. The RB's softer tip does exactly that.In a driver where you're sweeping off a tee, the extra height can sometimes work against you. In a 3-wood off the deck, it works for you. The other piece that matters: players who struggle to hit fairway woods off the deck are often fighting a shaft that's too stiff in the tip for that club type. Even if the RB feels like too much shaft in your driver, the shorter swing and more controlled tempo of a 3-wood changes the equation. A little tip activity helps square the face through a tighter arc. If you've tried a BB or WB in your 3-wood and still can't get it up consistently, the RB in a lighter weight class is worth a try.

The older Red Board shafts like the RF and M+ had a very obvious kick at the bottom of the swing — you could feel the tip snap through impact, which was great if your timing was right but punishing if it wasn't. The new RB is much smoother. The tip is still active, but it loads and unloads gradually through the whole swing instead of kicking all at once. It's easier to control, doesn't balloon on faster swings the way some of the older ones did, and the overall feel is more premium. If you played a Red Board from 10 or 15 years ago and liked the concept but not the harshness, the new RB is worth a fresh look.
