Tube rings vs. Dovetail

Just wondering if for a C11 a dovetail bolted into the mirror cell and the corrector cell (as it is standard now) is stiffer than having a dovetail with tube rings around the aluminium tube?

On the same line of thought, I see all RCOS systems have two plates on each sides, no rings so would two plates make the assembly more rigid and less prone to flexure?

The C11 is a fairly heavy scope. Just trying to figure out if the current holding system is enough and flexure free.

As always thanks for your feedback. Much appreciated
