When I got my Sinar 8x10 a couple weeks ago, I set it up on my Gitzo S3 with the BH55. The setup was rock solid and I was happy and content.
Then I tried carrying this beast over my shoulder. Camera slowly flopped over. I made sure the rail clamp - and everything else - was tight tight and it flopped over again. On the BH55 ball! There's so much weight sitting up so high over the mounting point, that with the whole thing at a 45 deg angle over your shoulder the actual force on the ballhead must be way over its load rating. And I definitely don't like the idea of having to white-knuckle crank the knob down on my almost $500 ballhead.
Bottom line: I use the 8x10 on the Bogen with the PT head now, and everything else on the BH55. The PT head is quite a bit easier with the monorail anyway. I wouldn't hesitate to plop any lighter 8x10 field camera on the RRS head, but there just seems to be too much stress on it with the big tall monorail. And I'm afaid I'll prematurely wear out my BH55 is I keep cranking down on the ball like that. Don't you think that's bad for it? Usuall jus need the slightest little turn to lock it up tight.
I might try an Arca Z1 or something else with an 'aspherical' ball if I want to use a ballhead with such a heavy camera.
