Which Half ball head are you using as there maybe comparability requirements/issues
I find the Hybrid/Combination clamps useful, ie ones with Arca Swiss & Picatinny 1913. You can get those from the likes of Really Right Stuff but they are only compatible with their heads or for example the Leofoto LSC-50 which I'm currently using. Made in the Far East and not quite the quality as RRS but it is well made for the money and doing the job very well. On another setup I use a Novoflex Q=BASE II which I'm quite I'm fond of too, though that one's Arca only.
