Bridgestone Tour B XS, e12 contact ball review/測試!～上集

最近買Bridgestone Tour B XS和e12 contact球來用，看看Bridgestone的球有沒有更好。Bryson DeChambeau， Tiger都用Tour B XS這款球。就是針對揮桿速度在105mph以上的球友，我就不自量力的用看看，來感覺一下這個Bridgestone的頂級球款是如何？而e12 Contact球款是給速度一般的人來用，像我這樣的想再增加個5碼距離的人。

當然這兩款都是三層球的結構，製作的技術都是一樣，也就是2層射出皮+一個大球心。它的皮說實在也沒有做的很薄，應該是因為Titleist的專利因素（專利會規定每一層的厚度）。很多台灣的製球工廠都可以把中間或外皮的薄度做在1mm或以內。也就是在球心意外的部分做變化。當然球心是關鍵。先不說這部分。

e12 contact是球窩裡有小球窩的設計，也就是讓球和桿面可以增加更多的接觸，以達到更多的能量傳遞。這是這款球的賣點，我也想知道這樣是否可以提升擊球的球速或飛行的距離？另外它的結構是3層。2層ionomer和一個球心結構。ionomer對我來說就是surlyn，都是比較硬的人工橡膠材質。所以它是走硬皮和軟球心的結構。

Tour B XS是三層，2層皮加一個球心。球皮是TPU射出的Urethane軟皮但沒有比鑄造的urethane要軟。所以這款球是走軟皮加硬中間層和軟球心設計（軟硬軟結構）。我看了Mygolfspy的資料，e12 Contact的硬度是61，Tour B XS是86.都很軟。至少以硬度來說，都是我可以掌握和使用的範圍。只是對於Tour B XS它是針對速度在105mph以上球友，做86硬度是否會造成撞擊的擠壓過大問題？

這會導致球變形過大，產生過多的倒旋和側旋問題。球的能量會外散掉，這個我下面會在使用上去說更多。以這兩款球的結構和製造的複雜度來看，它實在就很一般。一些台灣的代工廠都可以做得比這兩款球要更好和更複雜的球來。材質也是很一般，球心看起來也是正規料。噱頭在球窩上比較多。當然這要測試才知道。但以這樣的製造效果可以確保最小的不良率和最大的利潤。

我用Taylormade SIM2 10.5度/Ventus 5 R木桿進行室內測試。打起來球很軟，就算是tour b xs也是一樣很舒服。都可以感覺擊球瞬間可以把球擠壓的回饋。回饋都非常的相似。這是值得肯定的地方。在launch monitor上看到的數據，球速也不錯，但飛行距離就弱了點。而滾動效果都可以由20～25碼的實力。

Recently I purchase Bridgestone Tour B XS and e12 contact balls to try. Let's see how Bridgestone balls is performing and whether or not it's better than other brands' balls? Bryson DeChambeau and Tiger are using Tour B XS for swing speed over 105mph golfers and I would like to see if I play, what result is going to be? e12 contact is for average golfers but to seek for better distance like me.

In terms of ball construct, it is 3 layer ball with 2 injections layer (cover and mid layer) and 1 golf core. Honestly the cover is not really thin compared with other 3 layer urethane balls. I believe there are a number of manufacturers in Taiwan can make even thinner cover than these two balls without difficulty. They can make the cover within 1mm size without problem.

The e12 contact ball is featured special dimple design that the dimple has small dimple inside that is able to increase the ball contact with the club face for better energy transformation. That's the technology I would like to dig and know how it really benefits? Its 3 layer ball design with 2 layer of ionomer materials (cover and mid layer) and one golf core. Ionomer is surlyn that is hard synthetic rubber. In short this ball is hard cover and soft core design!

The Tour B XS ball is also 3 layer ball with 2 injection layer and one core design. The cover is TPU with injection urethane but it's not as soft as cast urethane cover. That's the biggest different between cast urethane cover ball and TPU injection cover ball. It's all urethane material but the softness is different. Of course it's softer than surlyn/ionomer.

The e12 contact ball compression is 61 and Tour B XS is 86. Both compressions are not hard at all and I can play it without problem. If your swing speed is over 105mph, the tour b xs might have too much compressing during the impact. With that the energy will be released and unable to transfer the power 100% to the golf ball. That's the ball compression's key.The more compressed you hit the ball, the more spin rates you get for both side spin and back spin. That's not helpful for the distance at all.

I use Taylormade SIM2 driver with 10.5 loft and Fujikura Ventus stock shaft Regular flex to play indoor. First of all, the feedbacks for both balls are very comfortable and you can feel the ball compressed with your power. Even though the compressions for both balls are different but when I play it, it's almost the same and hard to identify which one is harder of tour B XS.
