BARE, 

I hate to put it this way, but the major disadvantage is they don't work.
The TC switch has to be capable of handling heavy bi-directional current,
in other words, a low impedance device.

A hydrogen thyratron tube can be used, but requires special circuitry.
This technique has been explored by Richard Hull of the TCBOR.  I 
plan to try it too, but I've been too lazy, and busy making spun aluminum
toroids.
