Be real careful with the resistor choice.

A metal oxide or film resistor handles many times less surge than an OX or 
OY resistor. OX and OY resistors are 14kV and 20 kV pulse rated respectively 
without damage, and handle (OX) 40 and (OY) 70 watt-seconds for 100 pulses 
of 1 second at 50% duty.

A standard metal oxide is not remotely close, and paralleling 10 will not 
get them close. Even better MOX are only 10 watt-seconds, and not remotely 
close to the peak pulse voltage (which will not increase when they are 
parallel).

I've never actually had a single OY resistor used in a termination burn out 
from lightning, despite some pretty hard hits.  MOX are a different story 
entirely.

Either type works fine so far as reactance goes, unless the application is 
reactance critical. For a Beverage, reactance of either is not an issue.
