Better or not? That is a matter of opinion and your suggestion to do a
comparison is what I have been saying all along many times.
There absolutely is some unusual properties to the plasma. Just think of
just the bare basic cdi ignition with one single diode...that plasma is
incredible. With the SAME potential in the same cap, without the diode,
the discharge is what is to be espected for a typical CDI ignition spark.
Nothing special just a bit more robust compared to non-cdi.
By only adding one single diode to the cdi, the plasma burst is LITERALtLY
about 100 times bigger in volume - at least it was with a 47uf cap, which
of course is about 10 times bigger than a typical cdi cap of 4uf.
But still, even a standard 47uf discharge into ignition coil without the
diode is not very impressive compared to WITH a diode... SAME power
DIFFERENT results.
With an inductor in the system, we can get an electromagnetic punch to
actually move something.
So without diode, discharge the cap into the coil and see how high it can
launch a 5 gram neodimium magnet or something.
With a diode, same power in coil, do the same launch and see how high
it gets.
I think these tests need to be done to compare the mechanical work
being done.
I have done some of these tests early on like in my video where I show
launching some magnets off of the coil just sitting on a table.
My tests were not super controlled at that time but with the same
amount of potential in a cap being discharged with or without, I had
some magnets that were launched stronger WITH the diode. Again, not
very controlled tests...nothing was super precision but these are the
tests I want to do maybe in the spring when it warms up in my shop.
Also, I don't see anyone using a magnetic harness in these circuits.
I don't really see it as anything other than a bifilar (wound Tesla EM style
like the pancake coils) choke in between the transformer and high voltage
cap on the HV side of the tube. I never mentioned that before but several
things have given me reason to believe that is what it is.
Anyway, I think your proposed tests should be done and the comparison
of joules of potential in a cap(s) and with or without the mixing should be
helpful in us learning more.
