Chef Anton with 'Golden Shells'
Bob Kohler's routine, I believe, is very much based on Gary Oulette's Supershells manuscript. However it is a very excellent routine & DVD to learn the shells and I highly recommend it. The only thing that puzzles me is the bit that you can not perform it on television without permission....since it is so similar to Oulette's.
I have a set of the Golden Shells and loved them when they first came out. I use to perform often in the evening under a streetlight and they really Glistened/shone on my table. However my hands would get sweaty and picking up and displaying the shells was sometimes tricky.....compared to lighter, grippier, plastic molded ones.
