I have 2 to 3 ideas for what the ideal head would be. Before i pull the trigger and commit to tripod head with my funds, I would like to see what the community thought of the pros and cons of each setup.

Heavy 8x10 Camera monorail with extensions.
mostly portrait work or landscapes or cityscapes.
Tripod is a second hand Gitzo Systematic series 4


Head (1) To use one of the Ries heads.

This should give the most flexibility being able to adjust of two different axis. It will also be the best option for when I need to shoot straight down.

Head (2) 75mm bowl adapter, with 75mm bowl and a clamp.

This should be more sturdy because the camera has a centre of gravity that is closer to the base of the plate. I won't get as much movement, but plenty to shoot up or down. I also think this will be much lower profile and wont get caught on trees or bus doors as easily.

Head (3) combines both. Leveling base with ries heads

I can use the 75mm bowl to make sure the camera is completely zeroed out before deciding my movements.

What are your thoughts on these combinations?
