低彈道不再是速度快的人標配/Low trajectory fits normal speed golfers！~上集

在開球或打遠距離的球桿來說，彈道一直是一個很重要的因素。因為彈道高低會影響你的飛行和滾動距離，所以你的速度力量對於彈道來說是非常重要。在一般的揮桿速度和彈道關係裡，速度不快或一般的球友，彈道的設定最好是中或高，這樣可以得到最好的飛行效果。但我個人覺得，這樣的邏輯和做法在目前桿身和桿頭特性提升下，逐漸要說bye、bye了。

目前的木桿桿頭和桿身設計上，材質的強度要比以前要猛多了。好處是擊球的倒旋量比10年前的木桿要低300～600rpm。對於球速上也比以前要更快、更殺！也就是對於球的能量轉移上要好提不少了。所以飛行距離不見得會比較遠，但滾動性要更好了。就我個人的使用近5年來的桿身經驗，效能上、倒旋量、都要更好。

我一直以來的彈道都是中或中高為主，但近3年來，都逐步去改善彈道高度。也發掘一個東西，就是現代化的木桿已經可以讓一般揮桿速度的球友享受到低彈道的效果和距離。以前的低彈道，你的速度不夠，絕對飛不遠，就算滾的不錯，但也不會比中或高彈道的飛行效果要好。但現在桿頭和桿身設計要更細膩，把很多的問題都解決和提升性能。

我現在反而認為如果你用的桿頭是主流大廠的產品，配合上近5年的高碳布材質桿身，就算你的揮桿速度一般，沒有破百mph的木桿速度，一樣可以打超噴的低彈道球路，距離也不會比高彈道差。對於倒旋量現在的木桿倒旋量要比5年前的要低300mph。也就是新式的木桿可以讓你的球速加快，倒旋更低，對於飛行距離也沒有降低太多，滾動距離還會增加個5～10碼。

白話來說，現在的球桿，如果桿身是aftermarket，你的桿子會越來越猛，球速和飛行效果提升。現在我要做的嘗試是把桿頭角度從10.5度改為9度。這樣的彈道才能有效變低。就算你用10.5度，調整loft角度，打出來的彈道基本f沒有太大改變。所以我會用9度的來嘗試。這樣觀察彈道變低，飛行距離和滾動距離是否有提升？

Distance is always matter on your tee shot! Trajectory is the key to make your ball fly long with good distance. However, the trajectory is also related with your swing speed, if you are not a fast swing speed golfers with over 100mph speed, the mid or high trajectory will be the best fit for you to generate the maximum distance.

However, the updated shaft and head profiles are changing the trajectory theory due to the stronger shaft and head face. The material is increased the strongness for the graphite shaft and driver face to reduce the ball spin rate after the impact. The spin rate is actually 300~600rpm lower than 10 year's drivers. It certainly gets about 5 to 10 yards longer in distance.

I have been using and playing mid of mid/high trajectory driver for a decade, but in recent 3 years, I change to the low trajectory to make my distance remain the same or longer. Since the new technology and better material, it makes the ball fly flatter and fast, the ball fly not longer than before but roll better than ever.

Since the landing angle of the golf ball is about 30~45 degree, I can gain more rolling distance than ever. Comparing the landing angle over 45 degree with mid or high trajectory, I barely get the good rolling result. Why? it's the ball flying with better energy without traveling high to get the distance.

In the past, if your swing speed is less than 100mph, it's better to play mid or high trajectory in order to gain the ideal distance. Now if you have a good aftermarket shaft with recent 5 years' driver head, you can lower down the spin rate significantly, even though you are the smooth swing speed golfer.

Now I change the driver loft from 10.5 to 9 that makes my trajectory to low but the distance is the same or better than before. If you use 10.5 loft with adjustment loft to 9 degree, it won't change too much on the practical trajectory, but if you play actual 9 degree loft, you can feel the launch angle reduce sharply. The loft plays critical rule for trajectory.
