I was fortunate enough to have been given a Sachtler Video 14II fluid head and tripod about 15 years ago. It has served me very well for some DV and super 8 projects I've done over the years, and now that I'm shooting S16, I've been using it with my SR3 package. It's a quality and incredibly smooth fluid head, but I'm starting to get the feeling that it's perhaps a little under-powered for a fully-loaded SR3. The 14II has a 75mm ball mounting, and the sticks I have (also Sachtler) are single-stage aluminum.
According to the specs I found online, the Video 14II head is rated for a max. load of 33 lbs. and has a counterbalance system of 15 - 35 lbs. Completely assembled (with a full mag of film, zoom lens, matte box, battery, etc.), my SR3 weighs in at around 23 lbs. That said, it would seem that at least on paper, the Video 14II would work just fine with my SR3. However, in practice, while the head seems to pan and tilt ok with the camera attached, I just have the feeling that the head and sticks combination isn't quite up to par with what I should be using with a camera that's the size and weight of an assembled SR3, and I'm afraid that the entire assembly is even a little top-heavy with the camera attached.
In the meantime, I've been looking around at some options for a more formidable head and sticks. I'll probably want to keep it under $1500, so right now I'm considering some pre-owned options, like perhaps a Vinten Vision 11 or Vision 12 head with the signature Vinten gray aluminum sticks. I think the best option would be a 100 or 150mm mount, so any thoughts or suggestions would definitely be appreciated. Thanks in advance!
For some perspective, here's a photo I found (not my photo) of the head / sticks combination I have...
