EMWL - Practical aspect questions

As per topic headline: I'm reaching out to those who have ACTUALLY USED AN EMWL.

The question really has to do with "best practices" and reality of getting into and out of the water with this massive chunk of glass and electronics.
BOAT ENTRY AND EXIT discussions ONLY - PLEASE

I'm aware the recommendation is to jump in with all parts separate and assemble in the water.
That leads to my question about the usefulness of the reflex arm attachment with dual ball mounts ostensibly for use with a 3 way clamp to attach float and arm at a distant point.
I must be total fumble fingers as the thought of trying to attach a 3-way clamp, while in water, while not dropping a $2k+ lens into the depths, kinda eludes me.

I've watched the video where @Alex_Mustard describes taking everything apart to clear copepods from between sections, but never actually SEEN anyone do this maneuver.


My dry-land/ pre-trip imagination has me attaching the focus unit via bayonet and covering it, while soft case carry the reflex element and optic in a pocket. Then after rig handed off to me in water, assemble the pieces.
OR
Assemble fully prior to entry and disassemble underwater to clear?

Thoughts?
