Terry's filter question

["Tesla list" <tesla@xxxxxxxxxx>]

I have several questions about the components used in Terry's filter.

1. Since the safty spark gap acts somewhat like an MOV (a nonlinear resistor
why
use an MOV?

2. Whenever I see MOVs in protection circuits they are always shunted by small
caps as in Terry's filter.  Is this because the MOVs are slow?

3. I plan on using twenty 56 ohm 1/2 Watt resistors in series in place of the
100 Watt 1k resistor.  If the safty gap fires occasionally will the resistors
fry?  The instantaneous power is huge but the average power is low.

My coil uses a 15k 30mA NST
