I am about to purchase the Arca d4m. It comes with a Flipplock or a classic lock (i.e., a screw). In principle, I would prefer the Flipplock (which I understand is the same as the one for the Cube).
The Arca sales person said that with the Flipplock one should only use Arca plates, and not Arca compatible plates (as for example the RRS L plate for the S2, which I have on order, or the Arca style plate from Camdapter that works with their handgip). He suggested that if I want to use other plates I should go with the classic lock for the d4m.
Any thoughts by those who use the Cube or an Arca ball head with the Arca Flipplock?
