Jim,

At the time of the advent of the TCBOR gap, it was probably much
better than many other commonly used gaps at the time.  Many folks
recommend them now because they never compared them to other
gaps, so they have no basis for comparison.  Also, depending on the
coil's design, the TCBOR gap may work as well as any other.
For truly optimal performance, the entire coil's design must
be optimized, especially the transformer/ capacitor relationship.
The TCBOR gap is probably best suited for a somewhat higher
breakrate and smaller relative capacitor size than is commonly used
today.

I've found the best results with large resonant or LTR cap sizes,
and low (around 120) bps operation.  These systems seem to
work best with SRSG's, STSG's, and gaps such as Gary's
Vortex Gap.

Cheers,
John
