John C,

This is not necessary contrary to the findings of other coilers.  A larger
toroid will *not* increase the spark length in the case where the original
toroid is of the correct size or already too large.  See a recent posting
of mine for guidelines for proper toroid sizing. 

In general it would be
more correct to say as a general rule of coiling, that the proper toroid
size will give the longest spark, for a given power input, rather than 
saying that a larger toroid gives longer sparks which is an incomplete
statement.  In coiling, many things must be matched up as needed for
best results.  

As one works with coils, these relationships among the different parts
of the coils become more fully understood and appreciated.
