The Acratech system, including the Nodal Rail, is tops for adaptability and intelligent analysis and design for what photographers need. Large levelling bubbles on both ballhead and nodal rail. With the GP ballhead inverted, you can easily pan level and vertically. All parts are sturdy & precise, arca compatible. Costly, but you get much more than most other systems offer.
