不是用越強的碳布就比較好，因為強度太高，會完全沒有彈性。所以都要搭配不同噸位數碳布的混用，才能得到最好的效果。而高噸位碳布是桿身強度的特性。可以有效減低擊球倒旋量、側旋量、和提高球速等效果。這也是要提升桿身性能和穩定度，從材質下手最有效，但成本比較高。

基本上，碳布強度在40噸或以上都是所謂高噸位碳布！而強度越高的碳布，運用上也比較有限。通常都是放在特定桿身部位，提升強度做用。而比較軟的碳布就放在需要受力彎曲的部位，產生彈性效果。

所以別被一些行銷語言或文宣給誤導。因為高碳布的使用上會比較簡單，缺乏彈性或沒有折點的感覺。如果揮桿速度慢的人，會覺得用起來硬的回饋。所以揮桿速度慢的球友，要選擇桿身重量輕的桿身，才能利用高碳布的效果和優勢。

在高噸位碳布桿身，選擇“硬度”就是關鍵。也不能用一般你用市售桿子的硬度來選擇。因為強度高的桿身，往往打起來和得到的硬度頻率，都和一般數據不同。這時候就需要實際使用的經驗，才能選擇正確的硬度。


如果技師沒有實際使用，是無法選擇正確的硬度。看太多技師，都是沿用一般桿身硬度選擇方式在高噸位碳布。當然後面用的結果，就是整個打不動！尤其某日系桿身品牌的10萬限量桿身，聽到一些球友都說打不起來。


說完桿身材質，再說到桿身彈道。彈道的設定在桿身廠來說，都是以桿身的擊球起發角，也就是launch angle。 如果你看廠商的規格數據會有這一個。通常都是寫，高、中、低。也就是說，你要高彈道的桿身，自然選擇桿身的launch角度是高，反之，就是低反彈角。

It's not said using the more high modulus fiber, the better performance you will get. Technically, it needs to mix up with standard or low modulus fibers such as 20 ton and 30 ton modulus in order to create shaft kick point. If it's all made by high modulus fibers for the whole shaft, it will be unable to play as it's too stiff.

However, using high modulus carbon fiber is expensive and the prices are high for most of high modulus shafts, but you can get fast ball speed and low spin/side spin rates. 

There is important part to select the right high modulus shaft's flex. You can use common experience to choose the shaft flex with high modulus fiber material. I have seen many golfers got negative feedback on picking the wrong flex for high modulus fiber shaft. 

Since the shaft frequency is differed with OEM shaft (off the rock clubs). If you do not play it before, it's hard to get the right flex for your usage. That's why you need to have good and experienced clubfitter to help you out on selecting the right flex and shaft weight for you. It's highly required experience and usage for high modulus fiber shafts. 

Let's move on to trajectory. It's important performance for a shaft. How to know a shaft's trajectory? You need to check the shaft's specification's launch angle. It's indicated for low, high and mid. The high launch will get high trajectory and low will get low trajectory. The shaft specification would not show high, mid and low trajectory.
