Question about Rollei C6i

Take a look at the technical data sheet and the instructions, which can be downloaded from the digitec shop. The tripod has a 3/8" and a 1/4" thread (just turn the screw), or a ball head with quick release plate. So it should be pretty universal.

I've been using an almost 20 year old 900gram tripod with tilt arm and 2-way head, for a GH5 for filming, on foot, and would like a new one. Here's what I'm thinking so far:
- buy a new lightweight tripod on which I can also mount a video head if needed.
- many tripods don't have a tilt arm - I wonder if the new tripod could be without a tilt arm and what the differences would be to mine with a tilt arm
- I wonder if one tripod is enough, i.e. a light one on which I can mount a head if needed, or if I should buy one light one (with or without tilt arm) and one heavy one.

What does easy mean without head? Without a head is a bit difficult. At least one ball head must be on it, otherwise it becomes impractical. Every halfway decent tripod has a 3/8 inch thread for mounting ball heads, video heads, gimbals and others. Depending on how heavy the video head is, I would buy something more stable than this Rollei.
