If your preference is for a ball head, FLM offers four sizes in the pro line, the FT-series.
Balls range from 38mm to 58mm in size, and all the FT heads offer tilt lock, meaning you can lock the horizontal axis and only use front-to-back movement.
They are rock-solid and won't break the bank, either.
You don't state where you live, but if you are in Europe or Asia, FLM is readily available; if you are in the US, try B&H, though they may not yet have a full inventory.
If you are in Canada or the US, and have trouble finding a head, you can contact me through the website listed in my signature.
