I'm in the market for a new ballhead and having trouble deciding between the A-Swiss Z1 or the Markins M20. Down the road I plan to add a Wimberly Gimbal-type Head so I would like to keep my plates compatible.
With my two Bogen heads neither plates are compatible, so I can see how it would be an additional hassle to switch plates over and over again.
Thanks in advance for any help
