HFSC traffic shaping for voice

Hello

How do you shape your traffic when you have
one very "sensitive" class of traffic and "everything else".
By "sensitive" i mean that i need absulute priority for that class.
It needs maximun bandwith and minumum latency.

I am tkinking of HFSC. Is it the right choice ?
Any succesfull implementations ?

Does anybody know any good implementation examples ?

Thanx
