Hi Luke,
          There is a very simple method you can use with *any* coil at
all:

Get your system tuned with a terminal on top, then close the gap up
until the system no longer breaks out. The nett result is the same as
adding a bigger topload except that you are reducing topload voltage
by reducing secondary energy rather than keeping the same amount of
energy and increasing topload ROC. At the gap setting which doesn't
enable breakout to occur, you can then add a breakout point to reduce
the terminal ROC.
