The short answer is how tight you make the turns will have little real

That short answer is WRONG.
Use the RG-8X I would probably use the #31 core over the
43 . The poor mans 8 turns of coax 4-5" in diameter without ferrites
will probably actually work as well.
Define "work." The important thing a choke should do is kill common mode
current on the feedline that couples noise to the antenna and fills in
nulls in the antenna's pattern. That "poor man's" solution won't do much
for that. If "work" means it won't overheat, yes, it would "work."
Depending on SWR and feed line
dressing (always perpendicular to the plane of the beam the need for
choke at all� is arguable
It's arguable only if you don't understand the problem, or don't care
about noise or the antenna's nulls.
