經朋友介紹今天穿了這副新的組合，聽說Wilson Champions Choice Hybrid也是Federer近期的選擇。

這次直穿55磅、橫穿53磅，感覺還真不錯! 尤其底線抽擊很得心應手，線床有彈力也比較軟，所以抽起來像在使用鞭子。但是因為16G比較粗的關係，所以手感沒之前17G的那些天然腸線舒服。

另外就是如同朋友所說，Wilson的這副混線因為材料特別，所以也特別耐用，打完兩個鐘頭後，的確發現線床沒什麼損耗，希望這次可以用上3個月。

It’s all in the name. Wilson Champions Choice is a hybrid of two of the most popular strings on tour: Wilson Natural Gut and Luxilon ALU Power Rough. Combining the ultimate playability of a high quality natural gut with the durability, spin and control of a textured polyester gives the player the best of both worlds. For durability and control, use the Luxilon ALU Power Rough in the mains. For a softer feel and playability, use the Wilson Natural Gut in the mains.

Gauge: Natural Gut 16 / 1.32mm
ALU Power Rough 16L / 1.25mm
Length: Both strings measure 20 feet (6.1 m)
Construction: Natural gut
ALU Power Rough: Co-polymer (nylon) + Fluocarbon resin + aluminum fibers
Color: Natural / Grey

Update Aug 21, 2014:

The string finally broken today, amazingly it lasted for 8 months!!!

Update Sep 7, 2014:

The pro shop I went told me they are out of Wilson Champions, so I selected a closest combination Babolat VS Touch 16 (Main, 53lbs) and Luxilon ALU Power Rough 16L (50 lbs). Also just noticed 16L is a bit thinner than 16 (ie, 1.25mm vs 1.32mm), let’s see how long it will last this time.

Update Apr 24, 2015:

The string broke almost another 8 months, but the last 2 feels awful as I can tell the string bed was dead. So it’s better to change it every 6 months. Nonetheless, I can conclude that I’ve finally found a natural gut + poly combination that provides good hitting experience and most importantly economically sound.

Update May 3, 2015:

Almost got a Yonex VCORE Si 98 G, but give up at the end due to the spec. is almost identical to my Head Extreme Pro but stiffness is even higher (ie, too stiff). So I ended up restrung with the same combination, Babolat VS Touch 16 (Main, 57lbs) and Luxilon ALU Power Rough 16L (53 lbs). This time, it should be able to last till December at least.

Update July 12, 2015:

Strangely, the previous combination only lasted for just a little bit longer than 2 months, probably due to higher tension than usual. So this time, I went for Babolat VS Touch 16 (Main, 55lbs) and Luxilon 4G Rough 16L (53 lbs) to see if the new string (4G Rough) will produce a better touch and feel.
