邪靈退去：無差別硬度之亂/Does auto flex work！~上集

目前台灣很多球友討論的一款桿身就是訴求auto flex的特性，我自己是叫無差別硬度。就是適用不同揮桿速度的球友使用。聽起來很屌，但其實我很早就知道也配置這類的產品給球友來用。我不是用現在大家討論的品牌產品，而是市面上桿身材質以40噸或以上的產品，以美系為主的桿身就其實是無差別硬度。

以前的桿身軟硬度比較明顯是材質因素。以前桿身材質大多是碳布噸位在30以內，但在10年前，日本一些小品牌開始運用高噸位碳布材質在桿身上，現在幾乎所有不錯的桿身都是以高噸位碳布材質為主。所以桿身強度已經比以前要高很多，同時得到的效能也比以前要好。現在的選手開球距離也提升，部分原因也在這上。

為什麼美系桿身，因為美系的桿身尤其Matrix/LAGP和Veylix，我比較熟，所以都是這樣在配置給台灣和中國球友使用。這類桿身使用高噸位碳布材質，用50g這個重量級別和R硬度就可以讓70%的球友使用。甚至有時用R1，比R要再軟一個階級，一樣讓平時用S硬度的球友打得嚇嚇叫。有些測試文都在我的網站上可以去爬爬。

因為我試過不同硬度和不同重量，給不同使用者使用，得到的回饋和實際觀察擊球結果，以回饋來說，這類桿身都差不多，不會有很硬的感覺。都很簡單和迅速。沒有日系桿身那種彈性感。打起來可以說無聊但卻很有效率，也很穩定。不過也是因為桿身回饋簡單，所以這才是無差別硬度的設計基礎。因為我很少會配置給球友他目前用的硬度桿身，以我熟悉的桿身特性通常用軟一或兩個級別都可以。

其實日系桿身如果也是用高噸位碳布材質也是回饋很簡單，沒有過多”踢“的感覺。至少我用過的Fujikura、三菱、UST-Mamiya都是如此。當然有些桿身款式會有比較明顯的軟硬感覺，打起來也比較多的彈性，那是在桿身內部設計比較多30噸以下的碳布材質，讓桿身回饋可以更舒服和軟硬、折點明顯。

Recently there is korean made shaft auto flex that fits for all kinds of golfers to use. It sounds good for golfers to play without getting fit on shaft flex, but I have been fitting the single flex shaft to golfers since 5 or 6 years ago. I have been using the high grade of carbon fiber such as 40 ton fiber sheet or above and selects the R flex or R1 flex (softer than Regular flex) to fit the golfers with swing speed from 85 to 105mph.

A decade ago, most of golf shaft is using the carbon fiber below 30 ton that makes the shaft strongness not as good as current high grade carbon fiber. With such material, it needs to set various flexes for all kinds of golfer swing speeds. However, recent 10 years, the carbon fiber has been boosting for the strongness with better performance, stability and feel. That's the advantages from the materials.

I am familiar with LAGP/Matrix and Veylix shafts and they are using carbon fiber 40 ton or above carbon sheet for the products, I can use 50 gram shaft weight with Regular flex to fit about 70% of golfers in Asia. For some shafts, I can lower down to R1 flex for golfers to play. Even you play Stiff flex currently, you can enjoy the R1 flex shaft without sacrificing the consistency and performance.

I have been using and testing lots of golf shafts from Fujikura, Mitsubish Rayon, UST-Mamiya, LAGP/Matrix, Veylix, if the shafts are consisted of high grade carbon fiber with over 40 ton fiber sheet, it will be good for average golfers to get better distance, fast ball speed, and forgiving. Although the feedback is kind of bored as the shaft works very simple to catch your striking point without too much bouncing feedback.

The regular flex is good for average golfers with swing speed from 85 to 100mph, they won't feel hard during the play but it's not too soft from the usage. It's just as simple as you can image. You won't be able to feel the difference between R, R1 and S flexes. To me it feels the same. That's why for high grade carbon fiber shafts are good for single flex to majority.
