I came here looking for experience with the Manfrotto Nitrotech N8, and turns out this post is the only one mentioning it on the entire forum.
I have ordered the head and will pick it up later today or early tomorrow, and put on my old sticks with only the flat base for now. (would love to get the Flowtech if you guys think that's sturdy enough, and put it on a bowl - or get different sticks with 100mm bowl..).
I'll use it with both my BMPCC and Ursa Mini 4.6
