I did a bit more research and discovered that the Manfrotto 168 head is the older version of the 488RC0, which has a load capacity of 8 kg, so it should be okay with a Pentax 6x7. I even found a post at the Photo.net forum by someone commenting that the 168 head was okay for use with a Mamiya RZ67. Even if I divide 8 kg by 2, it should comfortably cope with the Pentax. The 055 is about "right" I would say. The 190 (you mentioned earlier) is a bit on the light side. I have the 055MF3 (carbon fibre legs) as well as a 190. I use a geared head, but a medium ball should do as well. And another recommendation: To reduce camera shake during a tripod mounted exposure and make for sharper photos, lockup the mirror, if you can, before tripping the shutter. The torque induced by the mirror flipping up can really shake a medium format SLR camera a lot. However, it's only really a problem with slow shutters speeds like less the 1/30 or so. It also depends on how long a lens you have mounted: longer lenses amplify the movement. I would increase the mirror torque/slap range to as fast as 1/125 up to about 2 seconds. As you imply, different lenses mean different resonance characteristics due to the slap. Longer lenses would be the worst for both amplitude and cycle length, I would imagine. Early edition Pentax 6x7's did not have MLU but it was introduced at one point and Pentax would even update non MU cameras. (Per Karen Nakamura's site).
