I would be cautious about crimps, unless the blurb
actually said the word 'solid'.

Crimps are relatively non-fussy about stranded vs. colid core
cable. For most combinations the same crimp terminal can be used,
although the ideal crimping force is slightly different.

Bare copper is a reactive metal, subject to long term
oxidation, or verdigris, or other chemical attack.
To make a reliable crimp joint onto bare copper needs
something that first of all cuts through any oxidation
that may be there, and then makes a gas-tight connection.

This needs a heavy gauge crimp, with sharp serrations
down the bore, used with the correct tool.

If you're using pre-insulated crimps (ghastly things that they
are) then the vagaries of trying to deliver a controlled force
through a squashy plastic sleeve give rise to far more variation
than solid/stranded cable.

Add to that pre-insulated crimps in a light gauge
with smooth bore, or at best rounded crinkles down
the bore.
