Hi Greg, 
On this subject you will find as many opinions as there are "Biological exhaust
systems" (Everybody's got one.) To my knowledge, no one has done a long-term,
controlled, comparison study in coils identical except for filter chokes. Most
evidence is anecdotal-- ("Such-and-such seems to work for me, it must be
right.") The cost of such a comprehensive study would be beyond the means of
most Coilers, since it requires a statistically significant number of
transformers to "run to failure". Perhaps the Geek Group could undertake such a
project. For now, this is still an experimental science.
