The upgrade is not very expensive in the grand scheme of things. I would just get the magnum personally. I'm getting the K120 kit for mine which is 300 hogs and comes with the top with larger knockouts for the KT120's and the KT120 tubes themselves. It's nice that Rogue does that sort of thing. They're a nice company to deal with.
Rogue Cronus vs Rogue Cronus Magnum
Hello Rogue Owners. Is the Rogue Cronus Magnum (KT90, KT120) better than the Rogue Cronus (EL34)?
