I've never heard of the Zombie until now.
The Vampire, sort of foam Voodoo, was a step backward as far as I could see. Sort of an attempt to get into the foamie craze.
The Sneaker, a larger, taperwing woodie was a big step forward. A really great design.
The Demon, a smaller diamond-airfoil design wasn't very well respected, but I built one and did OK while it lasted.
In retrospect, airframe design came in a long way behind power, reliability, pilotage, pitting, and judging as a deciding factor in who won the match.
The original Voodoo, with a good G15 or a Rossi in the engine room, was as good an F2D as any for a few years.
