倒旋和彈道高度決定你這桿子的特性/It's all about the spin rate on the distance！~上集

現代化的球桿，尤其的木桿類，對於桿子的特性都會有幾個特性可以觀察。一就是手感回饋，二是彈道、飛行軌跡，三是距離結果。而現代化的桿頭和桿身都在一個關鍵裡打轉，就是“倒旋”！倒旋有多重要，它決定你的球速、飛行軌跡和落地滾動性。所以在現代化球桿裡，分析倒旋量是非常重要。

影響倒旋量或產生倒旋量就是人的擊球速度，和觸球方式。在球桿來說，會影響倒旋的結果在桿頭部分，就是桿面設計和桿面角度。在桿身就是桿身材質強度、硬度等。所以我們看擊球的模擬器得到的結果，不能單純看一個部分，而是要去看整體的東西。這樣才能知道原因和解決之道。

現在新的桿頭設計都集中在幾個環節裡。一個是擊球倒旋減低，加上是低重心。這樣可以讓球容易飛到空中，同時具備低倒旋的快速衝力。效能上的表現會更好。球質效果會比10年前的桿子要更好。我在近5年所用的桿子比如TM、Callaway、Ping都是這樣的設計和表現。桿頭的倒旋量比以前的桿子要低20%以上。

桿頭角度其實現在的桿頭都做得更精準了。尤其桿頭標示10.5度，實際角度會是11～13度都有。但現在我自己量測的結果（幫球友們訂製和自己的球桿）都在1度以內的誤差範圍。為什麼會這樣？因為現在桿頭效能越來越有好。不需要去做大角度來讓桿頭可以更易打。因為把桿頭重心拉後，擊球反彈的角度更好。

同時擊球的初速可以更好，這樣球可以更容易快速飛到空中。如此距離就可以立竿見影。而桿頭重心這塊就可以看，目前桿頭設計都是把桿頭重量集中在底部，上蓋改用輕/強化的碳纖維材質。這樣桿頭重心更容易去拉後。所以桿頭在重心、角度和材質都有明顯提升，才能讓擊球倒旋可以壓低，提升球速。

Nowadays wood are focusing on three important fields, one is impact, second is the trajectory, and third is distance. Let's look into the details, if you check all the product descriptions, the woods' heads and golf graphite shafts are all concentrated on spin rate! How come is it so important that all clubhead and shafts are talking?

Spin rate is critical since it's related with the ball speed, flight pattern and rolling after landing. These three factors are all related the distance. Distance is always the thing golfers are trying to gain. Everyone wants more distance in order to get the good score. That's why the new woods are talking about to reduce the spin rate.

To effect the spin rate and generate the spin rate is your swing speed and impact. In terms of golf club, to change the spin rate is on golf club head and shaft. The golf club head is on loft and face material. The shaft is related with the materials and flex. Therefore, when we look at the spin rate from launch monitor, we need to know it's overall result on spin rate.

Now reducing the spin rate can bring better distance? The recent 5 year's wood head design is all about reducing the spin rate and low and back center of gravity. Since such design is able to allow golf ball flight fast and launch easier to the air after striking. With my recent 5 year's drivers from Taylormade, Callaway and Ping I have got similar results on the spin rate.

I compare with the drivers over 10 years, the spin rate is reducing over 20% that means, the ball speed is fast, more penetrating and better rolling distance. That's why I can maintain the distance without losing and sometimes I can get longer distance when I play woods. The advantage of new woods design are used carbon crown to save the weight and allowed the weight on the sole with low and back CG design.

It's all about the spin rate on the distance！~Part II
