Yeah unsureI haven't tried it but how it was described to me sounds like its an amalgam of a pool noodle and an inner tube ... but its easier to mount then cushcore ??
So in short, more weight, easier to install, but still has the inner tube ... so why the fuck ?
That said, my pal who explained it to a half listening Nerf said its better then cushcorre ????
Hope that helps you to guinea pig it for us.
