First and foremost, the use of the Built to Rule Shadow-Viper head was truly inspired. It's a great head sculpt on what was probably one of the coolest BTR figures around, and it suits the Red Shadows perfectly. The use of Flint's Eco Warriors tooling manages to capture the feel of a flamethrower as well as a gas trooper. Being one of the later moulds, too, it has a nice bulk and mobility that I always thought was something very under-appreciated about those later figures.
