I would not call a 120V secondary a downside at all.  In fact, its probably
better that it is 120V.
Since PT's are primarily used be entry level tesla coilers and for
"portable" tesla coils, having a 120V input
is a very nice feature as 120V power is much more readily available in most
people's homes and other venues which may be used
for demonstration purposes.  However, if you do have 240V, you can simply
parallel the primary (14.4kV side) and series the secondary (120V) sides of
the
transformers.

Plus, I am sure you get OOHH's and AAHH's with your pole transformer.
Almost all (non-technical) individuals seeing my PT during tesla coil use
think the PT is
just your ordinary 12V car battery.  They also refer to my MMC arrays as
batteries also!!!
