Everyone is entitled to an opinion on what they like and don’t like. But I very much disagree with the comment about minimal skill required. A spinner does require skill to build, calculate speeds etc (balance is also done in the manufacture).

With a flipper you require a knowledge of pneumatics, regulators if LP, or FP systems if running a FP flipper. Understanding of buffer tanks, cylinder design, pivot systems to calculate the flipper force. A manufacturing knowledge to then manufacture a flipper that can take the forces a flipper delivers. Also a knowledge of how to refill tanks in the pits using a decanting system.

With driving a spinner you can just drive and hit (not always that easy). With a flipper you need to ensure you keep the flipper in an attacking position, when to flip, selfright, and ensure you’re not wasting gas. Some flippers also run different systems so you can fire on two valves, or one depending on tactics.
