Dean Rayneswrote a review of Black Diamond Camalot X4 on September 1, 2017
I have been using my X4 set everywhere! Because they just seem to fit everywhere! I have pulled my C4 off my belt to only find the slot is too small and then find that the X4 fits. I don't feel any less secure on the X4s because of the smaller head. Some say the .75 head is a little floppy on the stem but I don't think its that bad, its just what you expect from a single stem cam like this.
