I recently started using SmallRig cages (Black Mambas) on my R5 and R5 Mk2 and find them fantastic accessories. You can attach a small arca-swiss plate to the upright portion (camera left) to make the cage an effective low profile L-bracket that allows full articulation of the LCD screen. Only quibble I have is the placement of the SmallRig brand which obfuscates the Canon brand. RRS did it right by placing their name on the lower portion of their L-bracket.
