So I'm looking at some lower end hoppers, Invert Halo Too retailing for around £40 and Empire Magna for around £50. How do they fare compared to a Dye Rotor that retails around £130? Both the Too and Magna are rated above 20 BPS so they're going to keep up with whatever gun I put them on, so what're the biggest reasons I'd go for the Rotor over them?
