Mitsubishi Diamana Thump Fairway
The Diamana Thump name has been used before in a line of iron shafts and in a hybrid shaft. The irons have been discontinued. The Diamana Thump Hybrid is still available, now a special order item. It is my all time favorite Hybrid shaft and has been in my bag for a very, very long time. When I saw the name thump applied to a fairway shaft I had high expectations, and the measurements of this shaft met them. Mitsubishi discontinued the Fubuki AX Fairway shaft in 2014. It occupied a unique niche, a fairway only shaft, 43″ long uncut, at $250 MSRP, with all the unique qualities of the premium Mitsubishi $400 driver shafts. The Diamana Thump Fairway once again fills this niche. At $250 it puts delivers premium quality at a more approachable price point.
As I worked my way through the measurement of this shaft I left torque for last. Everything looked very good, would the torque be low enough to compete with the premium Diamana’s I have been using in custom fitted fairways. The answer, yes. Tip zone torques of 2.3 in the 70 and 80 gram versions put it into that special class of shafts that can comfortably control the extra weight of a fairway and maintain club head alignment during a preimpact brush with the turf.
Radial quality of the review samples was 99.6% with a 0.4% standard deviation. Translation: shafts don’t get any rounder, don’t bother with alignment and use this shaft without reservation in a rotating hosel fairway head. Look again at those torque numbers. This is a high launch design, something most of us want in our fairways. The typical shaft that delivers high launch is also high torque. If the stock shaft in your fairway has a tendency to create hooks when you lean on it, you should consider replacing it with the Diamana Thump Fairway. Replacing your stock fairway shaft with the Diamana Thump will create a club you can trust.
I have built countless numbers of custom fit fairway metals with the Diamama Red and the KuroKage Proto TiNi driver shafts. They launch high, with adequate spin to deliver drop and stop shots. The Diamama Thump Fairway, at about 60% of the price, has a very similar design. It is a bit stiffer in the butt section which for those with an abrupt transition is a good thing. The profile of these shaft from high mid to tip is hard to tell apart. And they all sit in the same torque range. The Thump Fairway and the KuroKage Tour Proto TiNi have much the same hoop strength.
Here is feedback from my first sale, “Went away to Atlanta for a golf weekend with the new Thump shaft in my 3 wood. I was embarrassed hitting it consistently 250 yards in the fairway and 10 yards past my partners’ driver tee shots. Didn’t bother pulling out my driver the last 36 holes. Too bad it can’t help my putting!” Robert V.
