Jaganpvs,
Jagan,
Just a quick reply, for you've laid such a feast before me (including links) that it will take me days to formulate an adequate response. Meanwhile, if you really want to see the VV in action, look up the marvellous "You Tube" offering put in by Chugalug on #2549 p.128 of this Thread.
EDIT: Just checked: it's still there...D.
To the best of my knowledge, this is the only decent video of the VVs off the ground.
Cheers, Danny.
