Anyone Ever Try One Of These Twist Barrels?
 

Hey Guys; I saw this wierd barrel on Ehobby Asia, and I was curious if anyone here has ever tried one, or has heard anything about them?

I can't see this working because it seems like it would totaly screw with the back spin from the hop-up.

What do you guys think?

There's some info out there on their performance, from what I have read, they are good and accurate at lower FPS. But at higher than around 220FPS, the purpose goes out the window, and they won't work well above that FPS.

More lile 350 fps and they work like no other barrel can.
