日本 Japan Progress BB4 木桿心得review! ~上集

今年新購的木桿，雖然以前就試過BB4但只是朋友提供的試打桿，沒有太多時間和客制的機會。今年回台北就隨便買一個來玩看看。桿頭來說，比較圓，像饅頭，桿面比較方正。很典型的日本小廠木桿風格，打慣美系扁平的桿頭，真的有點不習慣。所以比較適合做短一點，也是我現在木桿的標準尺寸44“。這樣裝起來，配上桿頭視覺效果，就比較剛好。所以裝起來後就和Callaway Elyte木桿一起來進行測試，下場就是2支木桿一起打，每一支打9洞來看看效果和表現。

這次的桿身我是搭配Fujikura Speeder 569 IV桿身。因為它的彈道不會高所以希望這支木桿打出來的高度不要高，Speeder系列也是我固定選用的桿身，它的穩定性和手感都是在桿身裡頂尖。配置BB4我覺得很搭，握把用美國的Pure 黑色香橡膠握把。整支就是一個紮實的純黑風！打這支有5個月了，覺得沒有美系木桿來的穩定和遠。當初我測試BB4時就覺得它的性能沒有外面或網路上說的好，這次用下來真的覺得很一般。

首先它的彈道來說，算中彈道，擊球的回饋紮實，起發角比較高，超過15度。我設定這個桿頭角度是9度，所以桿頭重心比較後低，導致launch angle會比較高。桿身彈道算中，會在空中稍微噴一下高度，後面就還好，不會一直往上衝。球速快但沒有Callaway AI Smoke和Elyte要快。如果單測BB4會覺得這桿子很猛，但一比較後就真的還好。一個問題就是球在尾段飛的比較沒力，所以距離衝不出來。飛行距離在220左右！

它的非甜蜜點的回饋是比較硬，很明顯知道這球沒打到點。因為它的桿面比較方正，要打到甜蜜點會比美系扁平面要難一些，這也是我比較習慣用美系木桿的原因。另外方正的桿頭也比較容易會打到地面，因為桿頭重量比較集中，用手打的人多半不習慣的時候，往往會擊球前或擊球時會砸到地面，導致球的方向和距離沒有發揮出來。就算你把球桿的長度和重量都設定和你習慣打的桿子一樣規格，最後還是會影響操作。

桿身的特性很不錯，擊球的速度都很快，但桿身的回饋比較硬，沒有明顯的彈性或受力產生的折點。這也是它的倒旋量不多的原因，但滾動距離上卻不是很好，滾個10～20碼左右，這是讓我覺得有點烙賽。整體規格用起來和我其他桿子都差不多，只是桿頭的操控和擊球精準度，就是沒有其他美系木桿來的好，導致距離發揮就沒有美系的好。這個很明顯，所以很多時候，打3洞後就受不了，換回Elyte或Ai Smoke。

This year, I picked up a new fairway wood. I’d tried the BB4 before, but it was just a demo club a buddy let me hit, so I didn’t get much time to mess with it or customize it. When I was back in Taipei, I figured, why not grab one to play around with? The clubhead’s pretty round, kinda like a steamed bun, and the face is super square. It’s got that classic Japanese boutique brand vibe. Coming from American-style flatter clubheads, it took some getting used to. I think it works better shorter, so I went with my standard 44-inch fairway wood length. With that setup, the visual at address feels just right. I tested it out alongside my Callaway Elyte, taking both woods out on the course—each one for nine holes—to see how they stack up.

For the shaft, I went with a Fujikura Speeder 569 IV. I wanted a lower trajectory, and this shaft delivers that. The Speeder series is my go-to—top-notch stability and feel. It pairs well with the BB4. For the grip, I chose a black Pure rubber grip from the States. The whole setup is sleek, all-black, super solid look. I’ve been hitting this club for about five months now, and honestly, it’s not as stable or long as my American woods. When I first tested the BB4, I wasn’t blown away despite all the hype online. After using it for a while, it’s just… okay.

The ball flight’s mid-trajectory, and the feedback on solid hits feels good. The launch angle’s a bit high, over 15 degrees, even though the head’s set at 9 degrees. The center of gravity is low and back, which pushes the launch angle up. The shaft gives a mid-trajectory too, with a slight pop in height mid-flight, but it doesn’t keep climbing. Ball speed’s decent but not as fast as my Callaway AI Smoke or Elyte. If you only hit the BB4, you might think it’s a beast, but side-by-side, it’s just alright. One issue is the ball loses steam at the end of the flight, so distance tops out around 220 yards.

Off-center hits feel harsh—you know when you miss the sweet spot. The square face makes it tougher to hit the sweet spot compared to American flat-faced woods, which is why I lean toward those. The square head also makes it easier to dig into the ground, especially if you’re not used to it. The weight’s more concentrated, so if you’re swinging manually, you might clip the turf before or during impact, messing up your direction and distance. Even if you match the length and weight to your usual specs, it still feels off.

The shaft’s great—fast swing speed—but it’s stiff, with no clear flex or kick point. That’s why it doesn’t generate much backspin, and the roll-out’s weak, like 10-20 yards, which is a bit of a letdown. Overall, the specs are close to my other clubs, but the head’s control and precision just don’t match American woods, so the distance isn’t there either. It’s super noticeable. After three holes, I’m usually done and switch back to my Elyte or AI Smoke.
