【L-shaft】L Shaft ["Carbon"] fls3011 ["Straight"] [] 130 (13.0mm) 's Japan Review

It is highly durable (you can feel that it will not break unless you are very unlucky), and the weight is about the same as nylon-based products in the same class. It is expensive, but well worth it.

However, the following two points are my concerns. Well, it is something that can be easily solved.
The joint of the shaft loosens easily.
　(It loosens as much as a metal shaft. It is better to have an O-ring.)
Flight retention is not high.
　(If you don't like the flight coming off, you might want to consider a shaft ring.)

Durable and long lasting!
Flights won't come off!

My personal impression of the strength is that it is "better than nylon".
When it breaks, it breaks easily.
What you should pay attention to is "barrel weight" and "looseness".
When I used a 22g barrel, I broke several barrels in one practice session and it almost broke my heart.
If the barrel weight is around 20g, it will not break so much unless the shaft is loose or hit in the wrong place.
Some people say they have never had a single breakage, so I think the strength depends a lot on how the person handles the barrel and the setting.
However, it looks matte and cool, and the texture is smooth and comfortable to touch.
With the premium champagne ring, it is almost impossible for the flight to pull out.
The price of 2,000 yen including tax may be high,...
