Hanks tremoloarm?

[Rosegard]

Hi!
I watch the new DVD,and on some close up pictures you can see that the tremoloarm not looks like the standard one!
It's bent in a different way!What is the benefit of that,and can you buy only the arm and use it on a standard bridge,
or do you have to buy the whole unit!
BTW.
It was a fantastic consert I saw in Malmöe 14/11,and the DVD is supergood!
