Wow. Thanks for sharing those images. Incredible stuff.
People jumping EX-1 are amazing, too.

I'm willing to loan you my 645n, it's a monster. I have a Vietnam-era Air Force version of the RB67, too, with graflock back. There are some digital graflock backs, but none of them are full-frame AFAIK.
On a king DZ, I don't see many bigways...And even here at S'nore, they're just not there. Perris...I'm not in that class.

edit;
Just for giggles, tossed a 300mm (crappy zoom) onto my 40d and shot my own "art". I'll take the 645 up when I get back to Utah.
Shogo, the EX1 is actually quite easy to jump. Well balanced on an FTP, it sits very comfortably.
