Tom I know pritty much exactly how it was done.I am friends with his partner in crime and they both can do mambas with out a problem any of them.Water cobras as well and most elapids.The pitvipers are more of a problem.I was involved for a bit and stopped as I was injured in a fall.It can be done and there is some sound reasoning behind the idea of it.Altho it has many dangers involved.Sometimes I think the dangers are out weighed by the solid beifit if done right.
