Well they are using complex shapes in moulded carbon fibre much like C4 and they are using enclosed tracks unlike most other european manufactures.

We all say don't use so and so bands on that shaft, it will be over powered! Even though a thin lightweight thin shaft that would travel at a higher velocity would be ideal with skittish small fish at a distance. Being able to tame that oscillating shaft would be something that I think would put a gun design at the forefront. It's pure simple Newtonian mathematics/mechanics
