I would ditch the 128C and move up to the 501. I bought the 128C and found it was not rigid enough. It also had to be used with a balance bar to move the Center of Gravity of the Scope/camera combo further forward (this is very important for digiscoping ). The 501 has the extension plate built in and is a more rigid design. I'm going to get one soon. Neil.
Neil,
You're right, the Zeiss 85 is front-weighted; however, this hasn't been an obvious concern, as the tension adjustment on the 128RC handles this well, without being locked tight. I use an older model 128RC, on which the locking cam solidly fits a Manfrotto 200CZ1 ant-twist plate, attached with a 3/8" screw from a 200PL38 plate. The 128RC is widely used in Ontario, and seems massive at 35 oz, while the 501 weighs just under 53 oz.
That being said, I'd like to know more about vibration induced by having a scope mounted with its weight not balanced on the tripod head. I looked for reviews or other comments on the 501, but no luck so far.
Mike
