I tried the 701 head, but it was much heavier than the 700RC, didn't really make it with the light Slik tripod. 701 was extremely smooth, smoother than the 700RC, but the 700 was smooth enough, and I now have an extremely light package that I wouldn't hesitate to take on any outing. I live in NYC, don't own or use a car, so light is extremely important to me. I used to do video jobs with an assistant and a van - but that was a different time.

I also think a missed opportunity here is that with these cameras being so light it opens up to other ways of rigging, especially when traveling and lightweight.

Some examples being clamps and tubes that you can pop a small fluid head on (for my dSLR i have a little gitzo fluid head which is actually really nice (for this weight). And super clamps, suction cups or other types of clamps.

Monopods are cheap and great for stablisation (even just to add weight to the bottom of the camera when handholding, poor mans steadicam (and i have pilot anyway but the monopod is a damn sight easier to set up!))

I see lots of people 'modding' their cameras with follow focus, big matte boxes and rails who i don't really think they need to. Embrace the size and the lightness and see what other methods you can figure out for shooting and composing.

I have also tried the joby twisting things and wouldn't recommend those for video, too much twisting in that case. Neat idea, great for stills.
