Worker Flywheels

Worker's flywheels are legendary by now and have featured as a staple in the modding community for years.
 
These flywheels sport the grooved edges of the original design, but now they're made from ABS and are much more dynamically stable.
 
Many favour the grooved edge over the smooth flywheels for increased grip and less foam buildup, but they have been known to destroy darts in more powerful setups.
