This effects is just as pronounced with large toroids as with small ones,
perhaps even more so. A large coil that breaks out of a 56" corrugated
toroid may not even break out at all with a 56" smooth toroid (true story).

This effect does NOT hold up with larger toroids. The difference between a
large corrugated and a large smooth toroid are ... well ... large.

I've seen John's work: very nice. $126 is a very reasonable price for the
quality of craftsmanship that John puts into his work. Buy one if you
think you'll need one...
