I recently ordered a second C1 Cube head, and, as usual, it arrived with an attached Flip-Lock lever clamp. Unlike my first Cube, though, this one didn't come with the easily-removable hex screw, but with a circular screw with a circular hole in the middle - nowhere to attach a spanner or insert a hex key.
Trouble is, I use RRS quick-release plates on all my gear. Is there any way to remove the Arca-Swiss clamp and attach a RRS lever clamp? I'm out on a remote island at the moment, with no camera service centres who may be able to do this.
Failing that, can the Arca-Swiss Flip-Lock clamp hold the RRS plates securely, if it's something I'll just have to live with?
